Curling down leaves around top buds? Pic

I'm growing in coco and am in the 3rd week of flower. I've noticed the last couple of days that just on the top colas that the leaves surrounding the bud is curling down.. ? Never seen this before... Aside from this the plants look healthy top to bottom. Anybody ever experience this before?

I'm using house and Gardens full nute line at 5.8 ph (RO) and 77-82 degree temps.

hows ur humidity

Steady around 47-55, unless I do a foliar spray, then it jumps into the 70's for a couple hours. (Once a week for the last 3 weeks)

i had sum of that going on , with high temps but good humidity , but i chalked it up to underfeeding since i wasletting my soil get really dry , sorry i cant help but someone will chime in on this with a possible solution for u ...

I've had heat stress before on other grows and the leaves usually curl up taco style. That's why I'm confused here. I don't think it could be heat but who knows. Hopefully somebody on here has experienced this and can point me in the right dorection. Thanks

back off the nutes slightly, especially N.
if you are using calmag with N try cutting back

Not using any cal mag in with my nutes. I added a little Epsom in with my neem preventative application but that's it. Ppm going in is around 950, and coming out roughly the same. The PH however is 5.8 going in and 6.2-6.3 coming out. I've been told not to worry about the runoff PH since it's just the built up salts exiting the pots. But I'll try lowering the ppm and leaching a bit to see if that helps I guess.

Why are you pHing so low? I would raise it to at least 6.0, up to 7.0.
