I’m referring to the last 3 pictures in week 7. Those leaves are near the bottom of the plant, not getting enough light. I thought they’d yellow gracefully before finally crisping up and fall off. But these are dying gruesomely. Is this normal, or a nute issue? What’re those?

Small marks on leaves a concern?I noticed only a couple leaves out of a 4x4 gg4 grow show weird marks. Just wondering if it's cause for concern since it's my first grow. Otherwise they appear to be perfectly healthy, growing great and praying going on 4 weeks into flower.

Brown spots and holes Had snails and aphids earlier, but knocked them out. I'm these brown spots / holes in my girl.

Brown spots on bud site leaves?!halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.
