Hey sorry i didnt log in earlier. That ball on the right looks like a male flower starting to open. I would pick that off if you havent. I pick off anything that looks too male. Lol.
If you are turning lights on in the basement and there are light leaks it is possible. Just tape over them with gorilla tape. Easy to see during lights on. I make a larger zipper flap with the tape too on my tents. Stops zipper snags too.
I looked back again. I didnt realize you were so far into bloom. Should always include whole plant pics too i think. She is growing big balls. Pick them off and fix any stress. Heat is usually primary. Look for stale hot spots. I move my hands over the the canopy to make sure the air is moving and feels cool. I make adjustments as the weather outside changes and my fan speeds may change.
And watch the nutrient stress. When you see leaf stress , yellow tips, edges up etc. give some fresh water to dillute the built up fertilizer or available nutrients. Keep the roots happy and the leaves happy and the buds get super happy. :)
Thats my best advice. I adjust everything looking for medium green happy leaves as much as I can. Fans lights nute concentration. Leaching with some extra water sooner than later when we make mistakes.
Grow on!
