My leaves are turning brown

My leaves are turning brown and don’t know exactly why? Please help I believe it may be nute burn on over watering. I’m using fox farm nutes.

Anyone?

What week are you in and take more pics of whole plant. Also what notes have you been using specifically? You have to give as much information as possible so we can figure it out.

1st, how old?
2nd, what stage are you in?
3rd, are you adjusting your Ph?
4th, are you lifting your plant to determine when to water?
5th, are you giving nutrients and what are you using?
6th, etc, etc and etc.

Nute burn. Flush it or transplant or both.
