Thanks Imafam, I actually had thought I had dried it out too much just prior to this and so I was watering more...
I just was surfing the web and saw something about salvia varieties and a problem called Ammonium toxicity which has symptoms similar to my problem. One of the causes of it is keeping the water level too high which causes the ammonium in the fertilizer to build up
One of the solutions is to use a high nitrate fertilizer to offset the toxicity. Of course, prevention is best but...
One website said "If ammonium toxicity has occurred, raise greenhouse temperatures for the time being, discontinue the current fertilizer and leach the substrate. Ammonium does not easily leach, but itâ€™s important to leach out what you can. Re-water with a nitrate-based fertilizer and hold to this fertilizer until conditions improve. Under conditions of severe ammonium toxicity, gypsum (CaSO4Â·2H2O) additions can be made to facilitate better ammonium leaching. Apply one tablespoon of gypsum top-dressed to a 6-in. pot and water in with clear water. Follow with a 50-ppm drench of calcium nitrate 2 hours later. The ammonium binds with the sulfate from gypsum and becomes highly soluble, which allows it to flush easily out of the media."
So I went to look at the miracle gro and the majority of the nitrogen is Ammonium based...Huh...who knew! So while it wouldn't bother many of my other plants (over watered or not), salvia is very susceptible.
So now does anyone know of a good nitrate based nitrogen fertilizer??? I looked at the Alaskan Fish Fertilizer and that was mostly ammonium based as well.
