clones have only been in coco four days they have been fed once with less than 1/4 strength botanicare grow. should i go pick up some cal mag?? the PH is around 6 i dont have a meter yet. they are under a t5, temps around 70, 60% rh. water is reverse osmosis. i have proper ventalation and air movement in my 5x5 tent

I would suggest the Plant Problem area of the forum for a couple reasons:
1 you posted this in a thread that is a year old so you might be waiting for awhile
2 It looks like you have lil one in a cup of dirt ..... pssst this is Hydro forum we not use dirt :)
When you go to Plant Problem area download the troubleshooting form and post it in a thread that you start. The growers that patrol that area are real good at figuring problems out :thumbsup:

thanks tinytoon :)

oh its coco
