Deborah, we know your overall conditions are excellent and your water and fertilizer are correct. I think the first thing I would do is...

Ray, or one of his online calculators, will tell you exactly. When I run what you have given it is a very high ppm N. Yet, the EC is...

The correct amount of fertilizer depends on a number of things including temperature, amount of light, type of orchid, potting media...

Istvan, I have used Apera pH and EC meters. I think they sell in Europe. The pH meter uses a single calibrator solution at pH 7.0. Since...

I am starting to think that the pour-through procedure is better for identifying if your media is retaining salts. You get this...
