looks like maybe a calcium deficiency. What are you feeding them, and are you using the full recommended strength? Do you adjust pH... if so, to what? Are you using RO water? You might need some calmag.

Do you own the other two components of the Fox Farm nutrient system? You should also be using Tiger Bloom and Big Bloom as recommended on the soil feeding schedule. By adjusting your pH so high up on the 6.2-6.8 soil range, you are missing out on several things that are more available at the low end of the chart. Also because of upward drift as the nutes are used up and as they react to any buffers in your soil, your fluids will rapidly rise up out of the usable range, well before the container dries out. This means that for at least a portion of your watering cycle, some of your nutes are unavailable to the plant. Using the FF growing system, you will get better results from carefully adjusting your pH to 6.2 or 6.3, every time, even on the plain water you give between feedings.

Also, to get the full benefit of your calmag, it is extremely important to add this supplement to the water bucket before anything else. Once it has hit the water and the magnesium has converted to magnesium oxide (immediately) you can add the grow big, tiger bloom and big bloom as recommended.

I also like to recommend the 3 solubles, which also come in a trio pack. These supplements are worth their weight in gold, and will really supercharge your FF grow. One purchase is enough for several years of growing.
