If you are feeding extra co2 you should have no problem doing 64 DLI which is 1500 PPFD at the canopy level.But she's going to get hungry and thirstier. I do 46dli 1000 PPFD without c02 but i haven't tested my levels i think they are decent. your vpd is perfect for flower. I have a hard time keeping humidity down sometimes and 70 percent is not unheard of, once i start getting over 75 i get worried though.late in flower i try to be 60% or less.
Leromeanswered grow question 4 months ago
During the first 2-3 weeks of flowering it is not a problem for most plants to be around 70% rh for some time. There may be plants that dont like it though. Your plants are drooping a little bit, are they just thirsty on the picture?
