Looking good bro. I would back that lamp of the tops some though, with a 1k lamp you don't really want it that close or you'll get heat stress called light bleaching which it looks like you have. If you just back it off another 6" they should be ok unless you temps are running super-hot inside your tent as well.
I used to try to run my lamp right above the canopy to try to get more yield too, but I found over time that the end product is better with the lamp backed off some cause the plants grow much more healthily throughout the flowering process.
Anyway, just my two cents. Looking good and GL!
