Hi everyone. This isn't my first grow but this is my first grow in a DIY Aeroponic system. My plants appear to have been growing a little slow and they are falling over and twisting. There are some spots on one of the plants and a lot of them have brown roots. No smell though. Is it root rot? Almost all the plants have very pale green leaves. I'm running the Advanced Nutrients Connoisseur Grow A and B line along with their B-52 and voodoo juice. My PH is a consistently between 5.5 and 6.0 thanks to advanced nutrient's ph perfect tech. I'm about 2 weeks into the grow. What do you recommend I do? 4 of these are Barneys Farm Peyote Critical and the rest are barneys farm Purple Punch. I run my pumps at 15-15 cycle. 15 on and 15 off. My lighting system consists of 4 600W MH lights operating at an 18-6 cycle. Please help. I'm getting quite worried here. I've read a lot of threads but can't figure out what the problem is. Overwatering? root rot? too much light? I could really use a hand here.
