Problem: I'm having a yellowing and brown/bronze/copper like spots of my leaves . problems start occurring once i flip into flower. last harvest suffered because i wasn't able to fix the issue. resulting in small buds, weak plant, stem and stalks were very flimsy, dry curling yellowish leaves on entire plant, making it very hard to trim.

pH seems low, but that's just a guess. Usually broad die off like this points to fert burn. Can you post pics of the whole plant?

Check bottom of leaves, and rest of plant for any small webbs. It kind of looks like severe pest damage. Possibly mites

I def have an infestation of spider mites but was also wondering if it could be some sort of nute deficiency aswell.

do spider mites cause the bronze rust like spots on the leaves if leave untreated?
