New Superthrive formula fried my Lepanthes

[clintonsparsons]

I Sprayed "ready-to-use" Superthrive on my Lepanthes tentacula. I have used the regular superthrive on all plants for years, in high amounts.

This new product seemed so convenient, so I used it on my Lepanthes. All of the moss on the mount was dead and brown overnight. I flushed the mount with RO, but by day three the the dead moss was molding with a light blue fungi that looked like mineral deposits, but was mold. The moss already had cyanobacteria/algae in it anyway, but that was dead now, too, and became gross. It dropped seven leaves, and I only have two left that look like crap.

I carefully dismounted it, removes as much material as I could without harming the healthy roots. I drenched the whole mount in a Captan solution (1 TBSP per 54 oz.) I have more than sufficient air circulation, my humidity is set to 90%. What else can I do at this point? I have never had any mold issues of any kind. The mold was not growing on the plant it's self, but was feeding on the rotten moss.

I am just shocked that so many of you use superthrive original concentrate but this ready-to-use spray completely obliterated this plant. I sprayed an L. calodictyon as well but it only dropped two leaves. All of it's moss died as well so I went ahead and re-mounted it also. I have never mounted anything before, so hopefully it will be ok.
