Heat stress or low humidity?

[gittergreen]

My rh is 32% but has been as low as 25% My current temp is 80f and has topped out at 82f
Any thoughts would be helpful.
Thanks Gittergreen

NUTRIENTS and/or PH could do that to leaves, read up in "Grow Room" forum!!!! good luck!

Rh is to low will curl leaves up and leaves will even turn lime green from low rh need 70% seedlings 60% veg 50% flower around this range is ok low is no good unless in late flower then even 45% would help resin a lot
