First Organic Auto Grow 50x100cm 6 Plant

Introduced AlgAMic hoping it helps with both FrostedGuavas and the Bruce Banner, which seem to have some issues in form of dark spots on the leaves. Zrawberriez started to show the same dark spots since yesterday, so I am a little worried. I suspect pH-issues, but I still have to wait till my PH-meter arrives. Tap water in my region is moderatly alkaline and I didnt check PH as of now, so a little PH-down should help if thats really the case. Please leave a hint if you suspect anything else :) Overall Im really happy with the grow, the Cream Autos and the Ztrawberriez look amazing IRL, judging by the trichomes they should be ready in near future. Calendar for the Creams says 6-8 weeks S2H, so I think they are right in the middle of this range now. Ill see what this week brings and how they ll look on sunday. Ztrawberriez shouldnt be far behind. The rest looks like another 3-4 weeks, at least. Ill see...
