The grow guide below is for moderately clean tap water with a start EC of. You can adjust the amount of water needed based on the size of your grow. Coco growers frequently run into Ca issues. Learn how to use CalMag plus. The following feed chart is for starting weed seeds or rooting clones.

Ph should be 5. Use gentle lighting at 24 or 18 hours per day, and if cloning use a humidity dome to allow your young marijuana clones to take in water from the air until their roots form:. The feeding chart below is for small plants that have grown roots or for mother plants. After transplanting weed plants to a larger container water heavily and then let the coco nearly dry out before rewatering a few times to encourage root growth.

Lighting continues for 18 hours per day during this stage. Once roots are established stronger lights such as Metal Halide can be used. Mother plants will stay on this feeding schedule continuously. The amount of time spent in vegetation will determine the final size, a common rule of thumb is to flip the lights to 12 hours when plants are half the final desired height.

The feeding chart below is used once you switch your lighting to 12 hours per day. The chart below is based on 5 gallons of water. Watering frequency depends on plant size, environmental conditions such as humidity and heat, as well as the size of the containers used.

For plants in 5 gallon containers, I typically water every other day during veg and once daily in flower. The following chart is based on an 8-week flowering strain. The length of flowering for your specific strain may vary between weeks.

Same thing with autoflowering strains which begin to flower without requiring the lights to be adjusted from 18 to 12 hours. Learn more about trimming weeddrying it, and how to cure it.

The Canna Coco feed schedule above will show you the right amounts of Canna Nutrients you should use.The ideal pH for coco coir cannabis grows is between 5. Your goal is to keep the coco coir medium at a pH of 5. Varying the pH a bit in veg from 5. You want to go a bit higher for flowering to allow for better absorption of phosphorus and potassium. This ensures the roots get fully saturated and the runoff removes excess nutrient salts that could lead to nutrient burn.

If your runoff pH is too low or too high, you can adjust your next watering to bring it back closer to the proper range. Aim to get it down to 6.

Keep in mind that separate plants need to be monitored independently, especially if running different strains. Especially if you catch them early. Too high or too low pH levels will prevent the marijuana roots from being able to absorb necessary nutrients, something known as nutrient lockout. Weed plants suffering from nutrient lockout will show signs of damage, so monitor your plants daily and look for unusual symptoms. For example. For a pH over 6. If the pH of your runoff water is too low, say 5.

Once the runoff pH is back above the 5.

Keep an eye on the runoff going forward to try and keep it around 5. A decent pH meter is well worth the investment to test pH in coco coir nutrient solution.

Incorrect pH levels are the biggest cause of pot plant health problems among new weed growers. Get a decent pH meter, adjust using a small amount of pH up or down, stir gently, and test again until you get it in the zone.

Wiggle your pH meter around in the water gently to get the reading to calibrate quicker. Make sure to properly store it by adding pH meter storage solution or clean water to the cap and replacing it over the pH bulb after each use.

Every 3 months you should recalibrate your pH meter according to the instructions it came with to ensure accurate readings.If the pH of the solution that you add is outside of the acceptable range, some nutrients will be unavailable to the plant. Coco does not buffer the pH of nutrient solution as effectively as soil and therefore it is critical to set the pH of the nutrient solution inflow within the range of 5.

Because different nutrients are soluble at different pH, it is best to allow the pH to drift up and down within the range on successive fertigation events. During the majority of the grow your inflow pH should fluctuate around an average of 5. However, during the seedling and ripening phases it is best to target somewhat higher in the range 6.

There are two options for measuring pH: a color indicator test which uses liquid drops, or a pH meter. Other pH tests or meters, such as test strips, are ineffective.

These are a cheap and easy solution to get started. Many pH adjustment kits come with a small liquid drop color test kit. These are an excellent option to start managing pH. The color test is not particularly accurate, but pH does not need to be a specific target and it is actually better to allow it to vary from fertigation to fertigation.

The drawback to the drops is they become practically useless if you add a supplement that significantly darkens the color of the nutrient solution. Unlike EC meters, the technology involved in measuring pH is sensitive and it is worth avoiding the cheapest meters.

Cheap meters are unreliable and have short life spans. That said, you do not have to buy the most expensive meters either. We use and recommend this Apera Instruments pH meter. It comes with small jars of calibration fluid and is easy to use and store. All pH meters require maintenance and calibration. Many meters come with powder to mix and use to calibrate the meter. These powders are useless unless you have laboratory grade instruments to measure the amount of water to dissolve them into.

It is far better to purchase calibration fluid that is premixed at an actual laboratory. To maintain the meter between uses, it should be stored in either storage solution or calibration fluid. Most of the nutrients and supplements that you add to the nutrient solution have an impact on pH. The base nutrients lower the pH and certain supplements like silicon and SM raise it. Whether and how much you will have to adjust the pH of your nutrient solution depends on the pH of your starting water and your specific recipe for each stage of growth.

Give nutrient solutions several minutes to stabilize before measuring pH. To adjust pH it is best to use a product specifically designed for pH adjustment of horticultural nutrient solutions. They allow significant pH adjustment with very low doses and have minor impact on the EC of the nutrient solution. It should generally require less than half a milliliter of either product per gallon to successfully adjust the pH.

After adjusting, be sure to re-measure to verify. We recommend recording inflow pH values in your grow journal. Although it is critical to adjust the pH of the inflow, you should not be concerned with the pH of the run-off water. Your only concern with pH is always providing nutrient solution inflow that is in the appropriate range.When growing plants in a drain-to-waste setup and using a nutrient solution to deliver the plant nutrients, it is recommended that you feed with every watering.

Many growers follow feeding and watering patterns in which they will feed one day and then use only water the next day and similar variations but we recommend against this schedule as it causes plant stress. As a rule of thumb, you should start by watering once per day, and observing the moisture of the coco in the pots for a few days.

The plants respond better if you provide a constant level of moisture. Drying negatively impacts beneficial microbe populations in and around the root zone and creates a greater chance for harmful organisms to take over. Cation exchange capacity CEC is a property of soil and soilless media which directly affects nutrient availability. Therefore, by feeding with the nutrient solution at every watering, you can maintain relatively uniform chemical conditions at the root zone.

Maintaining appropriate levels of dissolved solutes at the root zone by following application rates listed on the feed sheet will create an osmotic gradient between the roots and coco. We simply recommend feeding with every watering as the best method to obtain higher end-product quality. Im useing water that is run throug a bigboy filtere, why is the ppm so high, and also can I get a phone number for one of your reps.

The reason for this is that softened water typically has a high amount of sodium, which is attained from salt. Most plants cannot tolerate high amounts of salt. Softened water essentially causes the plants in your garden to die of thirst. Not only does the salt in softened water hurt the plants you water with it, the salt in the water will build up in your soil and will make it difficult for future plants to grow.

Should I be concerned about salt buildups? Should I be flushing once an awhile or just have some runoff. Im new to coco any advice or things I should be aware of or look out for!! If you are using tap water you may want to implement a flush every so often. A sign that a flush may be needed is yellowing at the tips of your leaves or a white ring around your soil from the water evaporating and the salts being left behind.

Watering until you see run off will be a personal preference when using coco.And we stand by that claim with this new formula.

Although it is critical to adjust the pH of the inflow, you should not be concerned with the pH of the run-off water. Your only concern with pH is always providing nutrient solution inflow that is in the appropriate range. Many growers make the bad decision to provide nutrient solution that is outside of the acceptable range in a misguided attempt to correct run-off pH values.

This can destabilize the pH of the nutrient solution in the root zone and make nutrients unavailable. To avoid this common pitfall, simply ignore the pH of the run-off.Managing the Electrical Conductivity EC of the water that is available to the plants is a key practice to maximize the speed of growth and yield of the harvest.

In order to manage EC, you need to set EC targets for the nutrient solution that will be available to the plant. Just as the nutrition needs of a plant change during its life cycle, its optimal EC range also changes: starting low, reaching a peak during late bloom, and going down sharply at the end. In the chart below, you can find general guidelines for optimal EC at different life stages, however, there are differences between different nutrient lines. Therefore, you should start with the recommendations from your supplier.

However, if the supplier recommends EC ranges that are significantly higher than these general EC ranges, I would recommend finding a different supplier. In particular, you should avoid nutrient lines that recommend high EC ranges and frequent flushing. The EC that matters is the EC of the nutrient solution suspended in the coco at the root zone.

However, you can only measure the EC of the inflow and the run-off. The run-off EC is the best proxy for the EC of the nutrient solution in the coco. For this reason, your main task is maintaining the run-off EC within the acceptable range. Nutrient companies should provide you with both a set of recipes in a feed chart and a set of EC or PPM ranges for each stage of growth. The general ranges provided above are appropriate for General Hydroponics Flora Series. When calculating your target inflow EC, you need to start with the low end of the recommended range.

When considering the target EC for your nutrient solution inflowyou need to understand that the EC will rise between fertigation events. As described above, water is removed through transpiration and evaporation faster than salts are removed. This causes the EC of the nutrient solution suspended in the coco to rise between fertigation events. Therefore, the target for the EC of the inflow is always lower than the maximum acceptable run-off score.

As I discuss in more detail below, you are always working to maintain EC within about a point range. Inflow is added at the bottom of the range and run-off is kept from exceeding the top.

You need to start by setting a target inflow EC value, but your real goal is keeping the run-off value from exceeding the maximum. To determine the correct adjustment for your particular grow, use the following process:. You may or may not be able to use untreated tap or well water to mix your nutrients. The key consideration is the EC. Starting water must be lower than EC
