No worries, Dunkel -- Mischka specifically mentions in the guidelines that gardeners are welcome to post the sources of their equipment, supplies, etc. So long as you're not trying to sell it, go ahead and link away.
If I didn't know better, I'd say some other site had made you gunshy or something. :wink:
As to foliar feeds -- I've started feeding my alliums once a week with fish emulsion, and I often find that my tomato seedlings need a little boost sometime when they're small... I just hit them with MG today. In the past I've used seaweed extract with incredible results even after the first day or two of daily misting. This season they seem okay, but the peppers were turning a little yellow and slowing down so I figured I'd tag the tomatoes too.
Once they're in the ground, my fertilizers tend to smell bad, so I'd rather do soil drenches than sprays. (Don't ever spray fermented alfalfa tea... *shudder*)
