Is this a deficiency or heat/light stress??

Hey what’s up RIU. Currently mid flower on my second grow and I seem to have an issue that I cannot determine the cause of. I have dialed back on my nutes as a preliminary precaution. But the issue has not fixed itself. I want to believe that it’s heat/light related but would like some outside consultation on the matter! Please and thank you

i would say that theres some heat stress signs on your leaves, the edges crisping up the leaves are nice and green

Sounds good I’ve been having trouble cooling my tent as the weather gets warmer on the east coast. Took a risk and changed the on/off cycle to go on during the evening today hopefully it improves some.
