You should ideally have used larger containers as advised previously here and here.
The problem you have now is with your roots, they've probably got too wet (and possibly over fertilised) so will need to be allowed to dry out properly before you water them again. Also go very easy on adding fertiliser while the roots recover, go plain water for the next couple of waterings then 1/4 strength bloom fertiliser when you see her green up.
Can I ask what you're feeding them and at what strength?
Also how much water are you giving them and how frequently?
