You can start giving them a LIGHT feeding at about 3-4 weeks. Then if they seem to be taking to that after another week or two then start increasing the fert. At seedling stage there's more danger in over-feeding than under-feeding. And most new growers tend to over-feed and over-water.Quote:
As for nutrients. What will they live on if i dont feed um? There is no goodness in rockwell and as soon as the roots are big enough they are going in the nft system for some serious growing time.
