Purple Queen show some spots on the leaves, what do you think it is?The middle plant show some spots on the leaves, what do you think it is? 😜 Note: I lower the PH in my autopot system to 6.1. Normaly my bat mix have enough nutrients for the first 6 weeks. The dark color is because of the higher PH > to much Nitrogen intake I think.

Leaves curl on upper new growth and mid but not lower.I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Help with weird deficiencyBCN is starting to show some form of deficiency. Given that it's in its 9th week, we are debating whether we should finish with a flush and harvest or try to fix this. Can someone please give their advice and opinion. Have attached a picture of the trichomes, not perfect though.

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??
