Plants/buds look nice. The one plant with the light green looking edges it looks like a magnesium deficiency. Is this plant younger than the other two because it looks like its still in a preflower stage? Either way after looking up your nutrients I feel you may be having a nutrient "Lockout" situation. What's happening is you more than likely have an over abundance of either Potassium or Calcium or both which is locking out magnesium absorption. Even though shes in preflower you should still use a vegetative feeding schedule on her. They need more calcium/magnesium and potassium once they are truly in flower. If you give it to them too soon and they aren't using it you can wind up with an excess of them in the soil. I would suggest giving her a flush with plain ph correct water (2-3 gallons)measure the run off ph and ppm to see where they stand. I would flush her until you get the runoff ppm down around 300-350 ppm then add your nutrients to the last half gallon of flush water. You may need to feed her differently than the other plants until she is truly in bloom. Some time these nutrients make claims of ease of use but don't account for potential issues arising. To further explain the issue certain proportions of nutrients need to be followed to prevent nutrient lock out. Example: 4 parts of Potassium to 2 parts Calcium to 1 part Magnesium is the ideal proportions that need to be followed. Each nutrient excess has the potential to lockout the other. Since she is just starting to bloom you have a week or 2 to speed up her recovery. You can use a foliage spray of 1 teaspoon of Epsom salt (Magnesium Sulfate) to one gallon of water. (1/2 teaspoon Epsom/ 1 gallon of water etc.) Try to spray her until the point it's dripping off the leaves be sure to get under the leaves where the stoma are located. ** Do not spray her while she is under the lights it could magnify the water droplets and leave burn spots** Best time is just before you turn off your lights or very early in the morning before you turn on the lights. Put a fan on her and allow her to dry off before she goes under the lights. Do this twice a week until she improves. I would not suggest using this as a root drench because it could lead to another nutrient imbalance in your soil.๐
