Hi Linda,
Thanks for the response - and sorry to hear about your "recent experience."
I think you're probably right about the overfertilization. I recall reading that you couldn't really overfertilize with the Urban Farm product, but maybe I fertilized too often or the small containers were a problem.
Unfortunately, I fertilized my seedlings again yesterday when I watered
! So I just went out and watered everything again (particularly the plants showing any signs of distress) really well, hoping to flush out at least some of the excess fertilizer.
Fingers crossed!
Anne
