Help! My rescue phals are growing new leaves, not roots

[Leobaby]

I posted a while ago in August about a few phals which had severe root rot and lost all the roots.
I tried the sphag and bag method, and those two just molded and disintegrated and ended up in the trash.
apart from the two dead ones, I had 3 more. Two normal ones and a mini. I put them each in a glass of moss with water, suspended above it.
The mini just gave me two tiny 1/4 inch nubs, roots. And it's growing a new tiny leaf. The two normal leaves left are all wrinkled, quite badly.
The other two phals, regular size, have grown no roots at all, since August, but they both started a new baby leaf, and have the older leaves wrinkled.
I kept all 3 under growing lights, together with my other plants ( a few other phals still in bloom, a a cyclamen and a an Anthurium. ).
So what am I doing wrong?
Why aren't they making any roots? I will not try the sphag and bag method, since it killed my other rescues, but what should I do? I even tried some root stimulator (Wilson brand), and still nothing.
Also, when should I plant the mini that has those two tiny tiny roots coming?
thanks you.
