Sweet thanks for responding and I shall keep them in the cups until the second set of leaves...and question if I transplant the little ones into smart pots with fresh soil will I have to hold off for another 3-6 weeks before nutes start coming into play?
They say that two weeks is an ok time to start and to make sure you start at 1/4-1/2 strength at first. That depends on your soil though. If you are using FFOF, they say on it that it is fertilized for up to 30 days. Now, if you go to their chart for schedule feeding, if you use their line, they say you can start two weeks after it sprouted. So take it with a grain of salt and, when you do decide to start, just start with very light feedings, then build. Less is more haha.
I have only used bloom nutes, but the grow nutes work the same way, in that, you kinda follow a schedule of water,feed,water,feed..etc...and obviously allowing the soil to get kinda dry while it's young to promote root growth.
This is just some things I have read around on the forums. So many people say so many different things haha. Hope that helps some.
