Kelly, if you have a deficiency, using more of the same might not solve the problem. Orchids in nature get a constant feed. You can use more than one fertilizer and alternate every few waterings. See if that makes a difference.

Years ago I started using Jerry's Grow that everyone was touting. It started out great with a flush of growth and slowly, over time, I started having poor growth. For the whole time I used it, I had infestations of false spider mites which I had never experienced before. As soon as I stopped it using the false spider mites disappeared. If you are depending on only one source for your plant nutrients, you may run into problems.

I know fantastic growers who only use MSU and for a much longer time than I have. I have used the RO formula of MSU since early in 2008 and am very pleased with it. Just out of an abundance of caution, I still supplement occasionally with seaweed based extract, fish based and other types of fertilizers. You have to experiment and find out what works for you.

Marni, that is very interesting. I had never heard that rotating fertilizers could be beneficial. I learn something every day.

I think you should contact Ray, or go to Slipper Orchids forum to read about K lite.
I use it for more then 2 years at about 50ppm N but with every watering !!!
Not once a week .5-6 times summer, 3 x on winter and LOVE it.

I have been reading about it on Slipper orchids and I see a lot of people are having the same problems as me. Chlorosis, decreased vigor, and then fungal rot.
I ordered some MSU, I'm pretty frustrated with the Klite.
Sam, do you use r/o water or municipal water with Klite?
I did notice some spider mites in my terrarium too. Never had a problem with those before.
