can u tell me whats rong

ok first off i gave my budy two of my clones from 1.8 and he veged them under cfl for like a month i took one back to use as another mother. at the same time i gave him two clones from my 2.8 anyway he had them for like two weeks he called me and said something is rong with the plants i had him explain to me how the leaves were turning black and yellow ya when i herd that i was like what??? so i had him bring me all three plants i took pics that day or the next oh ya i keept them outside when i got them back but keep them away from my other plants its been like almost 2 weeks and the bigger one seems to be doing better but the 2.8 look about the same as soon as i got them i gave them some water and nutesbut im not shure what the problem is. any thoughts would be cool

it looks like it could be nute burn of some sort...or maybe a shit load of stress...just keep loving them n chill with the nutes with the clone...the still young roots are very vulnerable and fragile....

dude that looks bad. i dont really know what it is, they might be underwaterted and dehydrated.
Peace

they look VERY STRESSED or overwated or over nuted
