Too much light?!?

So i have some 10 day old girls growing and they are turning yellow at the leaf bases and veins. I have not fertilized at all or overwatered but i have 2 240W LED panels above the four. I could not diagnose it as any nutrient deficiency either. The soil they are in is FF ocean forest.

Here are pictures.


Please Help! I took one of the lights away to test out my theory.

May be some sort of deficiency. Your soil is lacking something.

Whats your PH?

well last time i grew with same soil it was around 6.2. i gotta get a new ph checker
