PH Nute Lock!!

You may not be doing your flush correctly.... flushing means running 3x the pot volume of water through your plant.... so if you're growing in a 3 gallon, you need to run 9 gallons of pH'd water through her. I would run as much water (ph it to about 6.5) as needed until the runoff measures 6.5pH... then let it sit and dry out. When you start your nutes again, give only 1/2 strength. I'd be willing to bet, though,, that your current problem has nothing to do with your nutes and is ONLY a result of the wrong pH... Calcium and magnesium need at MINIMUM of 6.0pH to be absorbed by the plant in soil... 6.2 is ideal... so don't fall into the trap of thinking calmag is going to help - it won't help at all if you don't have the correct pH... Good luck!
