I think the right plant may have gotten watered too early this last time.
That's already an issue. Your plants probably won't die but its hotter than they prefer. Your goal is the plant's leaf temperature at about 78F. If you're running LEDs, this would put your grow room at between 80F-84F. To be 100% accurate, adjust your tent temperature to hit about 78F leaf temperature on your plants using a non-contact thermometer.I've turned my light up to 10, which the plants seem fine with. But my temps are climbing. It's into the low 90s...
How hot can they get before it's an issue?
Still, use the Photone app to adjust your light's intensity. You really can give your plants more light than they want or need ... when that happens the plants show light stress. Your on the right path and do turn it back up ... but only enough to hit your ppfd readings for your plants stage of growth.Thank you. I'm using the ac Infinity ai controller. I've got their ac unit, but haven't got it up yet - I'll need to make some holes in my room walls...
For now I'm lowering the light until I'm more mid 80s temp. It's at 8 until I see where that settles. I'll run to the hardware store and get the pass through I'll need and get the ac in place. Then I can turn the light back up.
Then this chart might be helpful ...I would suggest you look into DLI if you want to pinpoint the light energy you are giving your plants.
I use the Tent Buddy app to give me an approximation of how much light energy my plants are receiving in PPFD. The app also gives me DLI readings based on my PPFD settings so I can pinpoint both. I use this chart as a starting point then adjust to see how much I can give them without stressing them. I'm currently in week 5 of vegetative and my DLI is at 42.Then this chart might be helpful ...

I realize this references CO2, for our purposes, ignore that.
I wanted to point out that while daily light interval is important, ppfd is part of the equation in calculating DLI. I don't worry about DLI. I do worry about how much light my plants are getting based on their stage of growth. Not that DLI means nothing, but to me ppfd is the more important number.
However, if using DLI works for you, great. It's not wrong especially if it helps.

As you can see, the Crop Salt chart doesn't drop DLI at flip but increases it. I've found that not dropping DLI on flip tends to take longer and produce less bud sites than when I drop the DLI. Again, my experience. Yours may be different depending on the cultivar you have but so far I've used this method with everything from satives to indicas to hybrids and have had some pretty decent harvests.
