First Leaves curling

I started my first grow on September 27th, I popped 3 Fat Billy’s x Wilson, and 1 northern lights 5 x Wilson both bred by Masonic Smoker. medium is coco and perlite, currently getting fed 3 times a day, at 1400 EC or 700 ppm just bumped up today from 1200 EC, PH Is 6.1-6.3, light is Vipar spectra p2500, at 60%,temp is 78 during day 74/75 at night and 60% humidity steady, running an AC infinity 4 in exhaust, in a mars hydro 2x2, ( getting a 4 x 4 soon),
My question for y’all is why are my first set of leaves pointing down to the coco? And why is this one curling a little bit

Looks normal to me, but is that Algae growth in your pot?

Leaves pointing downward because the shoots are pushing it that way. No need to trip!

I'm curious how you feed it 3x a day -

Yes it sadly is I think it is from the light hitting the coco I’m repottingng them tomorrow because the roots are fully root bound, they exploded when I put them in the dunkin cups lol

Awesome thank you, and with coco grows it’s meant to be under high frequency fertigation, it’s on an irrigation system with drip feed beneath the surface
