Too dry to generate proper vpd.
Try to follow vapour pressure deficit / vpdchart.com. soory its in celsius


Use leaf temp -2 to -1 depending on how many watts your giving; flower use -1. Your current environment would be for late flower. Try to stay within recommended ranges as per chart

For high intensity light you should generally be at 81-84F.
Okay I’ll turn off the dehumidifier and give that a try. Thanks.

I agree, the plants will take off once you correct this VPD issue.
I then would see if you need too add anything as those plants seem to be growing it is just they are dry as a fart in their word.

Just be careful of humidity spikes if you turn off your dehumidifier, PM loves that. If you can set it to a certain humidity that would be better. If you cant then a lower humidity is better than a higher one and leave the dehumidifier on because you have a dense canopy. VPD is cool but its not something you need to stress . Many strains grow in desert conditions and some grow in tropical rainforest conditions so VPD is not very specific and is more a generalized. 43% humidity and 80 degrees will be fine if thats the best you can get. In the winter with the really dry air, my temps are around 78 and 30% RH and the pot comes out beautiful. Don't overthink it and you'll be fine. Lots of times mistakes and issues happen when you overthink it and try to micromanage every little thing. As I said in an earlier post they just need more calmag and and a little more feed and your plants will be happy.

Alright everyone. I have let you all down again. My three THC Bomb strains seem to be more difficult to grow. My one bubblegum is doing just fine. I've only fed with nutes three times this month, including just now. They need more than that. I'm just not as diligent as I should be, too lazy. I'm sure they'll bounce back, just gotta keep at it. I also dimmed my light a little to ensure its not light burn.

Dang man Im sorry that sucks, I came back to see what they looked like since my last comment. Did you forget to add water to the nutrients those are really burned?

I think it's the opposite. Not enough nutes. When I had that issue earlier it went away once I started giving them nutes, but I didn't keep up with that. If I lose one out of the four that's fine.

Alright, well, I found out why the three plants are struggling. The soil's pH is 4.2. Nutrient lockout. Going to add lime but the issue is the soil is very wet right now. So I have to wait before giving them more water
