What would be causing this!?

Hey guys this is my first indoor grow so just wondering what would cause my leaves to be doing this the one light was a bit close to the one plant so I moved that up but the other two plants that weren't really affected seem to have some issues also not sure exactly what, but if you guys had any ideas would be much appreciated thanks!!!

Never assume.

You're well into flower, and without knowing what you're feeding, I say back off the N because the tips are curling under. High N in flower can lead to heavy foxtailing as well.

What are the night time temps like in there?

I'm feeding them advanced nutrients two part system A+B and also giving them the line up of nutrients that advanced has thanks for your help by the way!!

Usually around 19-20 degree Celsius but we just had a heat wave the last couple weeks and at night it was 25 degrees in there and during the day it got up to 34 degree Celsius for a couple days

Burning endings are signal that light is too strong also some kind of strong wind
