Please help - not sure how to correct this

I have several plants that are showing yellow. When it happened to the first one, I thought nute burn. Not so sure now, as several are showing the same symptoms. These plants have been through so much this summer, into bud too early, back to veg., heat stress, and now showing flowers and luscious green growth. Please advise, I am so exhausted and frustrated I am not sure if I can go through any more. :confused: Attachment 293959
