So I figured that the ph was off, I adjusted that Two days ago and added some Black Gold Tomato Fert. The stem on my KC Brains NL was purple, it seems to be lightening back up though. The smaller, "droopier" plant is a NL Blue Fem, they are having very similar problems if not the same. The dead spots on the leaves are yellowish, older leaves curling, stems and fresh growth is turning purple... Im just having a problem with puting my finger on this problem. ANY help I.D.ing this thing will help me BIG time.
