I have 8 seedlings under 4 sixty watt flourecents
in my hydro system
On a few of the leaves are little brown spots, I've checked for Caspid bugs or any kind of bugs for the matter and found nothing
Do you know what this could be?

Are you using RO water?

Try adding epsom salt to the res 1-"T" spoon for every gallon of water.

I'm using tap water
I used to let the water sit 24 to 72 hours

Try the epson salt then.
