i bought some clones from the club today. Green Crack and they were cloned on Dec 6 2010. so a month ago. They started to root and i wanted to know when do i start them on nuets?
i presume rockwool. Answer straight away at pH 5.5-5.8 If you are checking EC/TDS/CF/PPM then start on a very weak dosage and test initial runoff to judge next feeding.
