I've had the same issue before on burning so I go pretty much

I do change this around depending on what phase I'm in, and I use the "Green Gene's" PK boost formula in flower and transition.

I had just moved the plants from under the ts100 to my sp250 and a bigger tent and took the pic 20 minutes after the move.
Showing the OP how much growth was achieved since he started the thread and was on the fence about the ts1000.
Does that explain everything to your satisfaction?
Flower the male separately, harvest the pollen, and make your own seed.
Win win for you
Anytime I have a good male I can flower out I consider it a blessing.
I don't think it's light burn? The closest the light has been was 24" above.
I was hoping to wait for outside to do a defoliation, but like you say I may need to do one soon.
I've defoliated these 2 times already.
I'll pull some leaves when I sex these plants in a day or 2.
