B Plant much much much better roots, A plant roots looking about 3-4 days slower than plant B. Plant B also has bigger and more developed leaves
B plant is on the left, A on the right.

The only thing I am getting curious about is the water level, it doesnt seem to be dropping at all.
The water temp is getting high? what should it ideally be? I can lower AC but it will lower the tent Temp to below 80 probably

They are to small yet to really uptake much water or nutrients

Your perfect man. Even 320 is close enough.

It's not air temps that matter, leaf temps do. If I remember right you are led correct? 80f is likely almost perfect for good leaf temps. I run my room at 84f ish. Humidity is also important. If ya feel like a good read on how temps and humidity affect your grow and want to calculate VPD I made a thread here.

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

Make another post for the water changes and such in a sec.

Finally understanding vpd got me like 4 feet~ in a month . Just explosive growth. Absolutely crazy .

curling caused by too much water?
I was also think I since my water levels havent really been dropping and my roots on plant B are getting huge, I should lower that anyway

1" below the net pot. That's for soil. You can't drown a plant. It's lack of o2 that creates what ppl call overwatering. Thats how we grow roots completely submerged. By keeping o2 concentration good. With res temps of over 80f you can start to see some of these effects. The higher the water temp the lower the saturation point for oxygen. With temps of 72-74f I have never seen it even at 77f with good aeration. 80f might be pushing it.
