Can you tell us more,like temps & stuff?
you need to watch those temps and don't take the "don't water too much" advice too literally I think mate
That soil looks really dense, especially on the first two You need a bunch of perlite in there.
Transparent one looks like it has been stretching. Get it closer to light (I assume yoyr using some sort of fluoro).
you should keep it
oi, bro transplant into equal parts perlite and your choice of soil, i use miracle grow, the african violet is my favorite, overwatering is seriously stunting your growth along with lack of light, thats what a 2 week old plant should look like. then put a 100 watts of cfl over each, they will all recover and astound you. dont give up!
uh, he says he waters it once a week and his temps are 30+
