They won't need ferts until 2-3 weeks into growth. If your using a soil that contains ferts already in the mix (which is not good) you may have to wait longer and may even stretch your plants growth. Go to a nursery and see if you can get Promix bx soiless medium. It is the easiest stuff to grow in. Also, if you can find a hydro shop, get some Fox Farm ferts. Get grow big for vegging and tiger bloom for flowering.
