Cheers Loafyboy!!! from your explanation ; I will continue to use standard mineral water till the white roots come through the seeds. From the point of transfering them to the root riot I will use mineral water of PH 5.5 and after the first couple of leaves come through, I will add 1/4 strength nutrients till they are ready to transfer to the wilma system.

Thanks again.
