On the subject of veggies being heavy feeders. I have my facvorite veggie fertilizers and they are liquid. One is Neptune Brand Liquid Fish and Seaweed fertilzer. Great Stuff!!!
The other is AlgoFlash. Fabulous. I used that on my tomatoes all last season but will be using it on most veggies this year. In fact already have used it on the eggplant and zucchini.
