Hello,
Everything seem to be going good a week ago and today is day 54 in week 8 and JUST THE TOPS of the plants, the very tiny small sugar leaves turning yellow. The bottoms and shaded regions don’t show much. I know these situations are hard to pinpoint but wanted to know if it would be more so nutritional or lighting? I know late in flower so going to be bringing down soon… under the scope I would say it’s at 95% milky, 3% clear, 2% amber….just don’t want to go any longer and risk things getting worse.
Current Situation:
-Led lights dimmed which give a ~700-800 par at the top of canopy right now
-Feeding at 1.2-1.4EC
-Ph at 6.1-6.3
-75F
-53RH
-Promix HP substrate
-Co2 @ 900
Nute line: House and Garden – wondering if somehow these are the problem...this phenomena happened last run too.
