smoke24answered grow question 4 years ago It looks like you are growing in a soiless medium. If that is the case, give her plain water ph'd to 5.9 until your runoff ph matches that number, should only take 2 or 3 gallons. Then let her dry out until that pot is nice and light, after that water her with a normal feed and calmag dose with your ph between 5.7-6.1. That should fix you right up. Happy growing.
