Leaves bright green
So I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

BT21 Probleme?
Hallo liebe Grower, bei mir ist BT 21. Kann mir jemand sagen warum die Blätter der Blütenstände so „Neongrün“ werden ? Liegt es an Nährstoffen oder zu viel Beleuchtung? Die Lampe ist recht nah dran da keine Luft mehr nach oben ist Wäre super wenn jemand einen Tipp für mich hätte

Seedlings with yellowing leaf edges
Any insight on what may be causing the yellow edges on these seedlings? I'm reusing FF Ocean Forest that I used on my last grow. I didn't amend the soil in these containers as I didn't expect they'd need anything before it was time to transplant. pH was good at last harvest.

Yellow leaves
Hi there, I have a Skunk #1 Auto plant, about 7 weeks old, at the starting of the 7th week some leaves started to turn yellow. I read two options, that it is an N deficiency, the other option that it is normal as the buds absorb the N from the leaves. Any ideas?
