(sugar leaves) curling

In my 6/7th week of flowering and my sugar leaves are curling down and in like fan leaves do when the PH is wrong. Everything else looks good (little nute burn). Any idea?

I've never had leaf curl because of wrong PH.. I'm guessing outgrown root space or heat stress.. Do you know what the peak temp is in your grow spot?? Also, how long have you been growing this plant, in what pot, and how long of veg?

6 weeks veg,5gal pot,75*, and yea I had mine curl...Fixed ph and I was good

Well too many nutes will cause leaves to curl down and you just said you had a little nute burn...well there ya go...

Ph can make leaves curl up or down...and sometimes sideways...
