Help!!!! NL auto hydro, Leaves have brown spots on fan leaves also some yellowing

I am growing a nl auto which is about 2 weeks old, about a week ago 2 of the leaves started getting brown spots on them, it slowly started moving to other leaves to where now some leaves are curling up and drying up!!! I'm growing in a hydro system i've noticed some lil tiny ant looking bugs crawling around also my rockwool is covered in algae so im not sure if that has anything to do with the bugs, somebody please help me out here!!!

Nute burn possibly? I have some 3 weeks in ffof soil and they looked like that after week one. They are fine now though, just watered through it. Figured the soil was to hot for seedlings.

dude the rez that you have needs to be blaced out .. when roots have light hitting them they will turn brown and rot, hints the rotting that you have goimng on..

I changed my res 2 days ago and the new growth is looking fine so hopefully that solves something.

I will get on that asap!! what should i use some elecrical tape maybe?

how do i get rid of root rot??!?!?!

look into using hydrogen peroxide in your res for root issues ive never used it
but i think you had too high a ppm or ph was off maybe
baby auto's do not like alot of nutes
you could just tape aluminum foil around you res
doesnt have to be black just light proof
keep the algae from colonizing
but at the same time ive seen over watering do this as well so maybe your roots or your bubbles where to far away from each other
if its fixed then it will recover

i doubt its to the root rot point

and it seems to be showing signs of heat stress the curled up edges/serrations and taco'd leaves give that away
and ive always had problems with rockwool
maybe next go around use something like perlite or hydroton and it will fix the algae on top
but that rockwool is junk in my opinion not for use with auto's just doesnt drain well enough
