I am working on 4 plants currently but only one is really growing. the other three have come to a halt. I havn't seen any improvement in like the last week. They are only like 2 inches tall. 2 of them are still in solo cups but the one that is in a bigger pot hasnt grown either. what could possibly be going on? i tried to post pics but they are too big to attach-does anyone have any tips on that too? Thanks for the input.
