Hi guys, as the title states I have grown medically for quite a few years. This is the first grow in awhile though. I can't seem to get these plants to be healthy. The purple stems are not genetic and I know they are either deficient or sick. I'm thinking maybe its a mag or cal deficiency because of the ro water, or ph lockout but I don't know for sure. I'll provide all the information I can think of but please ask me any information that may help diagnose the problem.
- Strain is King louis og
- Lights are 240w kingbrite led lm301h samsung, 3000k,
- Using Jacks 321 with ro water, 1.7 ec and ph 5.8 runoff at least 20%
- Growing in rockwool 6x6 (I did not presoak the cubes and just dunked them in light nute solution at 5.8, I think this may be my problem as my runoff has been 6.8 to 7 ph)
- Rh 50% temps 80F

I appreciate the help. Cheers.

Been some time since wet sets. But translates to soil as I do. Your PH is too high. Getting excess P & K. Need run off at 6.2 to 6.6 max. Work it down. Avoid stress.
