The droopy yellow leafs looks like over watering to me...

hello,
Looks like nute burn to me. From what I gathered, auto don't like a lot of nutes and need less than what the nute company says on the label. And therefore boosters are not advised. less is more.

Looks like nute burn to me as well, look at how dark some of those leaves are. Also maybe the start of nitrogen toxicity. Some of the tips are curling like mine did, before most of the plant got the claw.
