Not sure what the problem is. PLEASE HELP !

This is my very first grow. I mean who tf wants to buy weed when u can grow it for free right ? okay so basically I've just been experimenting with my girls. moving the light and increasing the humidity by placing a plastic bag over the pot. I'm running a 600w mh 3ft away . fox farm ocean soil temp ranges from 77-81 and humidity goes from 40-50 . I've given them water and this stuff called tapping roots that they guy at the hydro store gave me for doing business with them. I've heard that ur supposed to start under florescent lights for seeds .. but I've read ppl using 1000 watters the whole way thru . So these girls have been under the 600w for a little over a week now. Please help with any tips or if can tell me whats going on here that would be great

I'm still a newbie but I think possibly the ffof is burning your babies. Not to late to mix the ffof with either light warrior or happy frog and replant. I could completely be wrong. Maybe your light is still too close. Can you raise your light any higher? Kinda looks like nitrogen def or heat/light stress?

how do i delete this thread ?

idk u might be screwed on deleting the three but looks like n to me could be the lights idk I grow outside

Almost positive this is over watered. Im growing 10 ladies in ffof and some times they will burn the tips at young age sometimes, but they all have pulled through to be strong and beautiful so far.
