Update: All my girls were fed @Prescription Blend. My GT is looking better now with the cal-mag. New growth is green and losing the purple limbs. None of them are drooping n starting to look healthier. I’m thinking that the correct PH n getting the temps + humidity dialed in helping also. I also started using my light @60% 18/6. Overnight temps are now in the low 70s to high 60s .Daytime is mid 70s. CL
