Heat stress?
Heat stress and can it be saved? Had to go away for a couple days. Hottest days of the summer mid 90's, full sun, but well watered. This is my first ever grow (auto & outdoor) and I expected about 1 week left until harvest. Thanks

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

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?
