PK Good For T44 CLONES?

.

Having a bit of trouble with my clones. They're 10-12 days old.
They were stripped of the first node, which was dipped in root hormone (powder), after being dipped in 24 hour old water. They were cut with pre-boiled, sharp nail scissors.
Both the bowls that I moved them to within only a couple of seconds had been pre-rinsed with boiling water too.
Both opaque.

Then planted in Oasis cubes, misted mainly the plastic wrap covering, not so much the leaves, but the leaves have always looked moist.
Aired a couple of times a day.
About 22C, under 1 20W, 1 foot-ish long, warm fluor.

The stayed healthy looking for about a week, which actually worried me a little, then finally the leaves began to pale 3 days ago.
Now they're looking fairly sheepish, but I don't see any roots long enough to penetrate the oasis.

Would very weak PK be a good or bad idea?

not sure
