I just started, only on my second grow. So, I dont know much but if these were my plants I would be worried about underwatering, and maybe heat. I keep my tent at like 73 and use a moisture gauge for the soil. But thats just me. Im new lol.

I set temperature and humidity according to VPD (vapor pressure differential). At the temp and humidity shown in your photo you are at a VPD of 1.55. VPD guideline are:
.4-.8 early veg
.8-1.2 late veg to early flower
1.2-1.6 mid to late flower
I know a lot of people grow outside of these parameters, but at your VPD the plants are going to need more water( as already mentioned by @SoOrbudgal) . If they were mine I would reduce the temperature a bit.
They are still alive, I wouldn’t consider starting over yet! However 6 photos in a 2 x3 tent will be pretty crowded when they recover!

Can you explain VDP? How to calculate and benefits?

Google VPD and you will find all kinds of explanations and charts that tell you the value based on temp and humidity.

The Stonington Blend? It should only need calmag until flowering, then maybe just flower supplements. A grower on here did an entire grow with SB, pH'd water only until the finish. He said he'd use some calmag next time. I was two weeks from flipping to flower when I got sick, I only gave water at 6.8 pH and they were thriving, beautiful plants, no issues, except fore the cat tasting some leaves. Nice, big green healthy leaves, they were growing fast. Soon I'm going to do the same thing again, same strains, maybe pre-wet the medium with calmag at first. I noticed one pot looked more wet in your pics but I wasn't sure of your schedule. Do you think those 3 gal pots are enough for photos to finish?
