Has it been like that threw out the grow?
Are you watering and nutriing the same quantities for all your other plants?

Man looks pretty ruff

Not sure what yet feeding, not a Cana Nutes guy, but she is burnt up pretty good

Kick up some PK untill harvest, but all those burnt leaves are done.

I'll go out there n say....My guess would be Test/Check your PH tester then test PH of water.
Looks like you've got real high PH levels in your water n plants locking out nutrients/dying?Maybe?

What has ya ec been at . That problem has been going on a while . I think ya maybe been under feeding as those yellow leafs look kind a healthy but deficient . I could be massively wrong that's why I ask bout your ec . Maybe that perticular plant likes abit more food . Just my opinion

I think those leafs may of been bleached if maybe ya light has been too close , I don't think it's nute burn as suggested in previous post
