I have 167w of cfl's on one LA Confidential that I picked up from a local dispensary(medical and legally of course). Its growing in a GH Powergrower. I had been feeding her the GH 3 part formula but I switched to luca's formula about two weeks ago. I just put her into flower today. She is 4 weeks old, and I have been LSTing her. How does she look? She seems to grow every other branch purplish red. I think its just the strain but any thoughts? I run my ph 5.5-6ish. The middle pick the lights were on so thats why theres a yellow tint. All my leaves are dark green.
