no, not wet. damp.

Once top of the soil dries, I have to water it.
The microbes in my soil like to be damp/wet. I spray until the top layer is back wet again. I failed to give it a mulch. I usually use white clover. That doesn’t mean I give them a full watering. Only time I give them a full watering is when the pot is light when I go to pick it up. I know how
Much time it will take before my plants start drooping.

at 350 ppfd and I was still getting light burn.

I veg at 350 - 400 with no problems

I grow organically in soil, too. Just dont overdo it in favour of the microbes. Roots still like it better if the soil isnt fully drenched in water because they need to breath. And microbes can last easily for days without water. They go spore but the new water awakens them...

You can throw on top on the pots whatever you can muster, alot of different things can prevent evaporation, even chips from wood/bark. Im using clayballs different types. Also much easier to water then as the water gets dissapitated quickly.

If the weather tomorrow is sunny Ill be collecting bark and such, for a strict organic mulch composition.

Up your temps and add some epsom salts to your next watering. You're definitely experiencing mag deficiency, and it's quite common when new to LED.

You need to try to keep your temps over 80°F, because the lack of infrared light (like you'd get from an HPS) means the leaves aren't as warm under LED, even though the ambient temp might be the same as what you had under HPS. Once you get the environment dialed in, you'll see what LED can really do.

VPD is a useful tool to get your environment dialed in.
Room needs to be in the lower 80's and use an IR temp gun to measure leaf surface temps.
It makes a HUGE difference.

Temp and humidity are 78 degree 55 rh is what I aim for, drinking water every other day. watering top soil everyday just to keep top wet...I took the light out figured I just use it during flowering...Plants are a lot happier...I got an ES 300 and a damn vivosun light lol

Youd want to stay around 81-84 w leds, and start out with low ppfd. Is this a soil grow, no liquid nutes? Then be evven more carefull with amount of light. These strong white led lights are much easier to grow with hydro. If they alreaddy got damaged they will be shocked now and will behave like pussies for a while.
Qbs at 150w is a hard learning curve

I just bought a co2 monitor, soil ph pen, Epsom salt, and reg ph pen. Its time to fix this issue

ok nice. I use a vpd chart. With those
Temps what are you getting your rh too?

RH varies depending on the stage of growth.
I run close to 70% during veg and will lower the RH as the plant flowers.
Depending on the strain, I usually end up below 50% in late flower.
The drawback to doing that is it creates a high VPD at the leaf surface and stresses the girls more.

Never too late to mulch, friend. And it doesn't have to be a living mulch/cover crop. You could even use something like cardboard if you had to, though hay (such as grass clippings), leaves, bark, etc. would be better. Your soil wants a blankie.
