I went to the store and a friend works there he told me it might be nitrogen Deficiency. I added some (~1/16th of suggested dose) and backed the plants from the light as Im pretty sure they we're too close to the light (~10 inches)

If anyone else has a suggestion thatd be great as my friend brought me some bigger clones and the tips are already brownish, but you can barely tell, I have 25 plants... I jsut want one to live as this is more for experience while I get the rest of the gear.

I'll update with some new pictures soon!
