Calcium deficiency. Add some Cal/Mag to your fertilizer line up, or if using it already, increase the dosage. Affected leaves won't recover, but new growth should mainly be fine once this is done.

Removing dry, necrotic leaves
Should I remove the dead part of the leaves? Specifically remove the brown parts of the leaves and leave the green part to save them for trim? If so how could I go about removing them without getting brown crumbles everywhere?

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?
I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?

What’s that? Pests?
How can I get rid of this? I’ve spotted these marks on some of her leaves. Should I remove infected leaves or something else?

Schnelle Hilfe bitte!
I'm almost in the 3rd week of flowering and yesterday I stupidly defoliated a lot of leaves to let more light reach the buds, then I read that it can be harmful. I removed 80% of the leaves, is that really bad? Will I have less yield? This is my first grow. Thanks!
