Possible light burn?

1000w hps was 18 inch from top of canopy to glass on hood. Raised it to 20 inch. Temp is mind 70s during day. Hand test feels fine. Other buds closer to light do not have issue. Perhaps over fertilizing?

It's a branch. 3 plants. Then it's over feeding?

Some of the leaves are rolling in like a 16th of an inch around the edge.

Yes overfed. Lay off the nitrogen a bit. I have tops almost touching the glass on my 1000 and no light bleaching or burn.

No. Never flush anything but a toilet. Next time just pH treated water. You’ll be okay. But excessive nitrogen in flower can cause foxtailing among other problems.
