LEAFS DYING
The edges of the leaves are dry and black. Every single point of the leaf is burnt(black) or yellow...even some edges on the leafs of the coal are burnt. I guess it’s overfert...but I just flushed. Is it Ph? I haven’t checked in awhile. Is it they ready to be cut down?

Black discolouration on leaves
Okay so the problems with the black spots continue only on one plant. I tried reducing nitrogen and increased calmag to 4ml/g. I defoliated the affected leaves and sprayed with baking soda mix. 3 days later they're appearing again. If I don't get this fixed soon im gonna lose her

Grey spots on leaves and yellowing
The leaves are looking light green to yelloe and there are these dark edges on the leaves are showing up.. Has anyone experienced this before? It was happening a bit before transplant but now it seems to be getting worse. I just transplanted within 24hrs... Stress? Overwatering?

Hey friends, can you tell me what this could be? Should I be worried? It seems to be doing fine and it's the only leaf with spots, could it be due to some water accidentally falling on it? Thanks

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

Cold or hot extraction for antioxidants?
What preserves anthocyanins in our cannabis leaves better? If we want the antioxidant properties so we can use them for our benefit, which is better? Cold gentle extraction or use of heat? A traditional african practice centuries old makes tea from leaves to treat certain illness

which deficiency?
what deficiency does this look like? (specifically the plant with the yellow tips,blackish leaves,and brown spots on lower leaves) ph is around 5.9 but also i know my meter is probably not accurate. i thought i was underfeeding if anything,did have root rot.

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.
