Seedling are very light green and leaf curling

(Just copied and pasted from my grow journal)

Help! So the plants have a slight problem not to worried but would like to get it solved ASAP or at least know what I’m dealing with.

Problems are leaf curling on the first plant and the other plants seem to be a very light green, like there could be a deficiency in nitrogen. Maybe ph problems.

Temps do get a little high during lights on max on the meter said 85°F, lights off around 68-70°F

I water with tap water that I bubble for more than 24-36hrs ph the water to about 6.5-6.8

The medium I’m using is a coco based medium that is cleaned and has basalt in it called Tupur by Royal Gold.
I ammeded the medium with a 75/25% ratio of Earth Juice 5-5-5 all purpose and Earth Juice Verede Fire Bloom 0-9-3

I also misted them during lights on but I stopped because I feel like that could have been the problem with the curling because the light gets magnified by the water etc etc.

I also recently fed them a Compost tea just to get the microbes a boost. It contained 1cup ewc, .5cup alfalfa meal, 1/4th cup of high phosphorus bat guano. Bubbles for 24hrs then fed a little to them. Not pH’ed

I water whenever they feel light or when the first inch or two of soil is dry.
I don’t let it get bone dry.

When I water the run off ph comes to about 7.0-7.2.

Those absolutely do not need feeding.

Listen to hotrod here. Im a soil guy not coco and I know they are different but that still seems like alot of stuff to be throwing at those little girls they are just babies. But on to the leaf curling which seems to be on quite a few of those plants I have a grow room that runs mid 80s all the time. I'm lucky to get it down to 80 during these hot summer days and sometimes that 1st leaf set or two can be real susceptible to the environment and I commonly see this in plants this size because of the temps. What kind of lights are you using and how far away are you keeping them?

And water runoff ph means nothing. I tested that crap once and it was like 8.3 lol and I freaked out but the good folks here put me to rest and I just kept on keeping on and things are going great.

Definitely, I'm going to keep it simple and just water plain dechlorinated tap water for now. I never tried teas before and wanted to try it, but I'm gonna wait till later on in the grow to implement compost tea.
