hi, i started growing now about a month ago. the problem i have is im realy not sure when to start feeding. im using rockwool (nft). im placing the cubes in the system once i have around 7 roots showing. now before its put in there im using ro water straight. ive soaked the cubes in nitrozyme 5ml and the seeds aswell. the cubes have also had 5ml of formulex.

1. is it right to only give them ro water, or shud i be adding cal-mag aswell at such a early stage?
2. is 2 weeks a gd rough figure to be looking at the first feed?

its just after about a week my plants start to go down hill, they appear all dry. there colour goes a funny grey on the high ridges on the leaves, and the new growth appears burnt (but only when new, first sprouting).

plz plz if anyonebody wud be kind enough to help me out id realy appreciate it, and so wud my plants ha
