Why do my plants have the claw!? Leaves curling down. Edges burning. Heat? PH?

Well I go into my room this morning and my beautiful baby wonder woman has taken a turn for the worse. the leaf tips are curling down sometimes even making a full circle. and the edges are burnt on the top leaves but I do think that's heat stress but the rest of this just started. I took some albeit crappy pics but hopefully its better than nothing.

...probably overfertilized.

You are supposed to mix the fertilizer into water and use THAT.

Sorry, not funny but, yeah, they got the nute burn big time.

Ya I would say overfert and possible PH flux

Ok thank you very much! I appreciate it.
