SmylinPupilstarted grow question 4y ago

I’m thinking huge phosphorus deficiency. This is pink kush mid flower I’m trying to adjust with a runoff of about 6.5. Do you think it needs a huge dose?

Black marks on leaves of a slow grower.Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

Gray leaves on buds with a massive concentration of trichomes. What is it?No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?
