Added two USB fans to move air as temps were increasing over 30°C; this worked well as temps stabilized at 27° DT and 24° NT. RH also increased from 34% to 45% DT and 64% NT.
I started reducing light schedule by 2hrs per day. Will be at 12/12 in 2 days.
Keeping the lights at 30cm above canopy; DLI increased from 20 to 25; will adjust next week to a DLI of 35 after 3 days of transition. Definitely pre-flowering
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
