With just 15days to go, I’m starting their stress. Did a final defoliation and noticed their water uptake dropped slightly. Upping their nutes past the recommended and seeing leaf spots and slight burn. Trichomes are almost 100%milky, buds getting fatter.
Good transpiration there, I like your light intensity too.
At 950ppfd with the 12 hour light cycle, your Daily Light Integral is about 40 or so. You should be able to push it straight upto the 50's without stress, so I'd say you'll be fine.
Best of luck my friend
