Newbie with a Problem( i think ) 3 Weeks and Hardly Any Roots Showing through My Smal

hello everyone (anyone)!!!!!!
i have started growing 2 ganja dwarf lowriders and have been growing them in the small rockwool cubes for just over 3 weeks and i have read that you have to wait for loads of roots to be showing before you can translpant them bigger rockwwol cubes but mine hardly have any showing. Am i over watering hem to much or is it something to do with the enviroment and is it o.k just to put them in the bigger bits of rockwwol with only the minimal amount of roots showing.
much appreciated if any one of you guys who know what your talking about can help.

Hmm more info please... and pics. are you doing hydro? dwc? or simply watering the cubes every few hours? what about food? some root juice?

3 weeks sounds a heck of a lot for a small rockwool.

Potting soil can be your best friend.

yup put it in soil, it will help the roots breath better by trasfering excess water from the cubes and protect them as they emerge.

get some pictures up this is like being a blind doctor with no motivation

thanks to to everybody who replied and i'll upload some photos 2morrow. but i think i got more problems than that as know the bottom of the plants look like they are dying but when i upload the photos hopefully some of you guys can help me.
Thanks again peeps! and speak soon

i have been watering the cubes daily. i may have fucked up because i started giving them nutes as soon as the first leaves came through and was doing it everyday but read yesterday that i should be every other day.

thanks mate, what soil do you rcommend ? and would i have to buy new nutes as the ones i have are for hydro.

I had some clones that had no roots showing and looked liked they were going to die for certain. I transplanted the cubes into soil and today they are thriving. Another couple weeks and they will be ready for flowering. I think your nutes should be fine.

I'm using Sunshine Mix 4 because that's what my local store had. It works well but it looks like Sunshine Mix 2 may be more suited for pot. Probably anything with peat moss, perlite, gypsum and dolomitic limestone would be fine. http://www.sungro.com/products_displayProduct.php?product_id=2&brand_id=1

sorry to bother you guys and last time today i promise but would it kill my plants if i put my plant that is in the small plug rockwool cubes into the big rockwool even though there is no roots showing through the small one.
thanks in advance guys!!!!

no it wouldn't kill them. but like people said unless you really know what you are doing, you are better off putting it in soil or even coco.
