Someone Please help

don't know what's wrong with these plants it looks like it's burnt yellow leaves and the leaves are curling up it starts from the bottom and the bud is brown. Also this happens to different strains I know it's not nute burn if nute burn than it would be at the tip of the leaves

what are your temps/humidity? usually curl like that b/c theyre hot

Heat stress is part.

It's outdoor and it's been in high 90s and low 100s. It's not too much water or not enough water. Hatrodharley I think it's from heat stress and it's very humid outside.Also some plants are over 5ft tall so I don't know what's going on.

Definitely too hot and the bud looks rotted to me.How old is this plant?

heat stress, maybe lack of nitrogen

Can't use too much nitrogen it's about week 3 flowering. The bud does look rotten gotta do something about this can't afford to have bud rot.
