think you have it backwards, a clone can handle nutes at a reduced strength as soon as they are rooted.
a seedling will probably not need any for the first few weeks but whenever you start you should start them off at a very reduced strength.
bejay Reviewed by bejay on . when to add nutes I've read that with clones you shouldn't add nutes before they have three or four nodes. Is the same thing true when growing from seed? My seeds are just about to sprout there 3rd set of leaves. Rating: 5
