Orchid nutes will work fine. If you have access to Lowes, they sell the Better Gro Orchid Plus, which is good for vegetative growth, and the Better Gro Bloom Booster for flowering. They are pretty strong, so start off with 1/4 strength and slowly increase to 1/2 strength. Just make sure to only use plain water the last two weeks to flush out the nutes and improve the taste.
