Setup Information:
2 DWC's (Kush and a Haze) using 5.8-6.3 ph
1 Auto (AK hybrid) in FFOF, unknown soil ph
Lights:
1x200w CFL @6500k, 1x150w HPS. Both are on 20/4
Age:
Auto(FFOF) is exactly 1 month old and starting to bloom, little nute burn on edges but shes doin fine.
DWC's are at 3 weeks
Air:
78-85F, 50RH, oscilating fan
Nutes:
For the DWC's, I introduced 1/4 strength dynagrow liquidgrow 2 weeks ago when I did their first rez change. They're up for a rez change TONIGHT, but I want some feedback before I change it in case I need to adjust anything. I was planning on doing half strength nutes this time (1 TSP per gallon) during this rez change, or should I do more? I have no other additives or nutes going in, just the dynagrow liquid grow.
A couple of the lower leaves have yellow spots. They look alright overall, but a few leaves in both DWC's are starting to look like they're getting them. I dont know if it was due to a recent high PH (they were both in the upper 7's until I brought it back down to 6 3 days ago) or if they need more nutes. Any advice please?!
The little Auto seems to be ok, the spots are appearing on the 2 hydro/DWC's.
