Looks like they're canoeing a little but I would wait and see if it's just an anomaly or they really are stressing. I would say light stress.Am I seeing signs of heat stress or wind stress on these plants?
Ambient temps around 84F with leaf temps around 75-77F. When the oscilating fans blow by they do move quite a bit but nothing too drastic, considering its the same setup i've used in the past. Something to worry about or nah?
Do I see the beginning of nitrogen w possibly magnesium deficiency ?Am I seeing signs of heat stress or wind stress on these plants?

ya might ease the light a little bit if it gets worse, thanks for the input.Looks like they're canoeing a little but I would wait and see if it's just an anomaly or they really are stressing. I would say light stress.
have had mag issues under these lights before, been supplementing with epsom salt. Although i think its just the photos in this case, the camera exposure under these lights dont really show the plants accurately. but will keep an eye for sure.Do I see the beginning of nitrogen w possibly magnesium deficiency ?
How much epsom per gal. Be careful. To much causes other nutrients to lock out as a side effect. At this stage a little foliar spray w it. 1 teaspoon per gal distilled apply to leaves. Stop soil side effects like if you just start adding shit type of effects. Lockout. Mold. Rot, burn ( 1 tsp per gal strength)ya might ease the light a little bit if it gets worse, thanks for the input.

Leaf temps lower than ambient air temp? U put that backwards by accident ?Looks like they're canoeing a little but I would wait and see if it's just an anomaly or they really are stressing. I would say light stress.
There is nearly always a temp drop from ambient compared to leaves. Under hid usually about 2* and 4* for led in general. Those drops are used to calculate VPD.Leaf temps lower than ambient air temp? U put that backwards by accident ?
using 1g/gal at the moment but in the feed rather than foliar. I've read about and also experienced mag issues under these specific LEDs (gavitas). Maybe i'll supplement a foliar spray once and see what happens.How much epsom per gal. Be careful. To much causes other nutrients to lock out as a side effect.

Yea I noticed that too, it was much worse a week or so ago. I am in rockwool and they get fed on timers every hour, so technically yes they just got fed. I recently lowered the feed volume after noticing the bloating, maybe I'll lower it a tiny bit more.. I think they were getting overfed at a certain point cuz I was getting too much runoff too early in the day.Leaves look a little bloated too. Did you just feed them when you took the photo?

Yup exactly. I am under LEDs so they give off almost no ambient heat. It's cold where I am and the room is in the basement so I usually see leaf temps 7-8 lower than air temp. @Moe.Red is spot on with the 2-4 difference, but that's in the summer for me.There is nearly always a temp drop from ambient compared to leaves.

Thanks my man!You are dialed in nicely and the leaves look very good. I love the way you have the fans over the canopy. Looks like you are kicking ass with this one.
I would suggest not going with that much of a dead-end. The dead band works like this. Lets say you have the Humidity set at 60. The troll master will not turn on the dehumidifier until the humidity gets to 70 percent and it will run the dehumidifier until the humidity gets down to 50 percent. Basically the lower the dead band the closer to the set point the humidity will stay.Starting to see some flowering sites on all the plants but ran into, not really an issue but something im curious about.
I have a trolmaster controller and I had the deadband set to 5% for the RH up until this point, but now that the plants are really going, the humidity reaches the set point very quickly. And since theres a hot start delay function, the RH will go above my setpoint before its safe to kick on again. So as of right now I just set my deadband to 10%. I don't really mind to be honest but if theres an easy solution to have it fluctuate less, i am all ears!
yup same, hugos. i think theyre 6x6x6what size grodans are you using just picked up the hugos
ok so this is exactly what im familiar with when i see the word deadband. However, it seems to be the opposite with this trol master controller. So im used to working with deadbands exactly how u described but this one works so that the dehu will turn on at 60% which is my setpoint, and since i have it at a deadband of 10, it will continue to run until it hits 50%. It was bizarre to me at first, if theres a way to switch it i have no clue how.I would suggest not going with that much of a dead-end. The dead band works like this.
