Just curious about what you all use. I like Miracle Gro, and the Master Gardeners at OSU are split on SuperThrive, though I may give up on it, a couple of people have done pretty well-designed studies that say that it does nothing. I love Maxi Crop for seedlings and plants that are rooting, and Quick Start for repotting and new plants.

For foliage plants like Episcia, I bump up the nitrogen by adding unflavored gelatin packets mixed with a quart of water, and Miracle Gro added to the appropriate dilution.
