really need some help cant figure out whats wrong

i really can not figure out whats going on here guys it was a whole lot worse but its still happening... they are in a 2x4x5 room with cfl's still in veg need help plzzzz

the last one is okay i think it just looks a bit vein y

it's hard to say. can you show a pic of a whole plant. it looks like under fertilisation to me right now. judging by the pale green leaves, purpling leaf stems and the necrotic tips.

i was over fertilizing them at the beginning, that's what i though to i just gave them a hefty dose of N

does anyone else think anything of this?

What type of dirt/nutes yo using? How could I say what to do
when I don't know what ya done? If yo haven't fed I would say
feed.

im using a soiless mix with humbolt verde nute

there's more to it my friend. diagnosing plant issues are hard. i can look at you rplant and see she is under nuted. then i need to ask why is she undernuted...


overwatering, underwatering, over feeding, underfeeding, high humidity, low humidity... disease, pestilence... apocolypse... it's all there. most likey you need to up your feeds. what makes you think you were over fertilising before?
