Wanted to share my experience with K-Lite fertilizer. 14 months ago I switched to it from MSU RO water because I've heard a lot of good things. Well, people say for a reason if it ain't broken, don't fix it. For the first six months, my plants were growing really well, I would say even better than on MSU. And then their health started deteriorating rather fast. I've had several major fungal and bacterial outbreaks and it seemed like no fungicide/bactericide would help. The new growths of many plants became chlorotic and generally weak. My regular bloomers would refuse to bloom. I also grow a pretty large collection of gesneriads and tropical Ericaceae (Vireyas and Neotropical Blueberries) and they were experiencing similar symptoms of nutrient deficiency. Two months ago I switched back to MSU RO water and already seeing some major improvement. I'm not saying K-Lite is a bad fertilizer, there is evidence that it works for some folks (maybe with supplementation of some other things) but didn't work for me.
