Appreciate the info, thank u. I am using ro water, so I know they are not getting any now. Weez, do I just wait and look for symptoms like red stems, yellow leaves, or start a diluted regimen at a specific time? I know seedling means a small plant, what I was questioning though, was whether there was a specific definition as to when it is no longer a seedling. For example, I didn't know if it was no longer a seedling at say, the 5th set of leaves. That kind of thing, but thanks for the info. As always, I appreciate the input.
