Confused about orchid maintance

[Ro3bert]

I have five "Mini"-Phals (Just Add Ice "Brand") but I have been told they may not be mini's, from Grocery stores (about 2 weeks ago). Should I fertilize them or wait?

I read that 20-20-20 is the recommended mix but according to all I've read the N should not come from Urea. All 20-20-20 brands I've seen contain N from two sources one (the lesser) being Urea. So is it OK to use it?

I have, at home, a box of granulated Miracle-Gro which of the 20% N, 8.1% is from Urea.

Of course it will have to be in solution of 1/2 teaspoon granules to 2 qts of water unless someone tells me differently. Now, how to feed; I understand once or twice a month but is it OK to top feed with a syringe?, and how much?

It has been/is suggested re-potting immediately (even in flower). In one I had trouble getting the plastic pot out the ceramic pot. The potting medium was packed tightly in the center so I loosened some of the potting (but not all), and re-potted it in a larger plastic cup and loosely added dampened sphagnum moss. Then placed it in a small bowl of tepid tap water up to the level of the top of the cup. Hope I've done right.
