Leaf Curl

Hey all, i've got a question. My great white Shark plant developed leaf curl after this mornings watering. I think thats to much nutes but i'm six weeks into flowering and this never happened before. I have the flush from general hydroponics but dont know if it will ruin my bud this late in flowering. looking for some opinions......... here is a couple of pics:

How's the heat/temps near the girls is the better question......looks like a little heat stress to me, beautiful buds though.....great job grower

Looks like the start of a calcium deficiency, I'd flush it and give some cal-mag and if that doesn't help then it has to be a heat problem.

i was thinking slight over feeding

wtf no dont flush u should be flushing anyways those look like thier almost done but cal def i dont fckn think so dont talk if u dont know wtf ur talkn about... heat stress or jus maby a bit to many nutes dought the over nuts but if u just watered its it could be but looks more like heat stress

agreed with mr mary j heat or over nutes

Id have to agree those babes look a lil warm,wouldnt flush so close to harvest, might shockm out

Heat or light stress... put a fan near her

classic over nutes , also look how DARK green your leafs are , they a little too green . couple weeks and they be ready , I would just be giving plain ph`ed water from now , maybe add a little honey in the water for taste ,
