ok, I have 5 plants that are about 3 weeks old. Four of them are in buckets, One in the ground. Two of them in buckets are the biggest, Other two are smaller, The one in the ground is small as well. Ill get pictures but, can I add nutes or fertilizer to them? If so what kind? Thanks for the help. The one is about 8-10'' high and the other is 6-8'' high. Others are smaller, Is this normal?
