The little women are growing up
Are your older plants showing some pistils on your top central bud?
I see some alternate nodes, so your plants are ready to flower (i think).
30klux 2700k 80cri are about 450 ?mol/m-2/s-1.
Are these values uniform in your grow room or only on some spot?
Thanks caio so i am indeed giving them to much light, i will lower the girls to where they were befoee, but they show the same thing..They seems in termal protection mode...try to not give more then 30klux on canopy level
450ppfd x 20 x 0.0036 = DLI 32
40klux
620ppfd x 20 x 0.0036 = DLI 44.6
Whats your temperature inside the grow?
To sustain a strong DLI they need 25/30°C leaves can't work at maximum efficency below 25°C.
Above dli 45 you need additional CO2 in your grow room.
Try rise your lamps and see if tomorrow do the same.
Whats your RH?
