Ross, Gin, and cb977,
Oh my goodness! I didn't realize that the spoon was a multi-measuring spoon. I just assumed the smaller end was the handle (I have some other spoons similarly that shaped are single measuring spoons).
boy do I feel like an idiot.
I looked more closely at my spoon, rubbed off the dust at the end I thought was the measuring end (it came in the fert. container so it was very dusty) and noticed a 1 Tbsp by the side I used. doh!
I had originally just looked at the smaller end (which said 1/2 TSP), thinking that the spoon was a single measuring spoon.
And, for those of you who have never heard of capital TSP being used for Tablespoon, all my grandmother's old measuring spoons and cookbooks that I inherited use a capital TSP for tablespoon and a lowercase tsp for teaspoon, hence my thought that maybe this was happening here....
Well, I'll be diluting the fertilizer I made up when watering and will be sure to mix the correct amount next time.
Good thing I only watered once with the super conc. fertilizer…I’m so glad I thought about the amount I added being way more than ½ tsp, but too bad it took me 12 hours to realize it!
As soon as I realized it, I flushed out the S/H one with RO water and ran a whole bunch of pure water through the two potted one (plus I’m repotting the potted ones this evening, so they’ll be out of the over fert. Water/soil within 24 hours of being over fert.
Thanks everyone, you guys are great!!
