i start seedlings in a party cup of patio plus potting soil. they just get water.
Then when they heve a few internodes I give them a drop or two of
Seagreen in there water. And I give them a bigger pot with more new potting soil (maybe some mycos or other root bennies) no nutes..(maybe more
seagreen)
I have not "fed" any of these seedlings below..I have given them AWCT 3 times in there life.
(Airated worm castings and Compost Tea.)
I only "feed" if a plant looks unhappy...so far..all mine are happy this year. :)
I do feed a few times in flower...every other week..
