Also your roots need darkness and those cups are clear. You need to make sure the soil has drainage holes in the bottom of the cups too. Planter pots are very cheap. You can even get nice bright white ones with dark black inside for .69 cents.

Ahhh, I did not know that!! Figures...soil is dark, and cold, and damp...much like my ex's heart. Thanks, I'll wrap up the cups in foil or something until they are healthy enough to transplant. I also made sure to drill drainage holes in the bottoms.

yo what up man! fill ur cups up with more soil, it will grow roots from the stem after a few weeks (2to3)....how old are they? yeah dont feed them anything tell after there 3 weeks old.. but they look fine to me, the soil looks a bit dry maybe a lil heat stress too but they look like theyll bounce back...
