rockwool has no nutritional value, so if your not feeding them much I believe thats the answer., your water & ferts need to be PH balanced, lower the lites, to 3-4 inches

whats your intentions, after germination? hydro methods? soilless? ???

your attempting advanced growing techniques, growing soil is more forgiving till you learn the strain you have

Thanks i have got some bubble buckets for them, the problem with lowering the light is that it seemed to burn them, however i will try this with my next attempt also have you an idea of the concentration of nutrients i should be giving them at this stage

I really dont do hydro, only solve the sick problems in hydro,

as to different techniques, dailing in the PPMs etc, go to the "advanced growing forum", and post that question
