Osmocote plus can come in many varieties. Some release nutrients quicker than others. So to say it will last "3 months" or so is invalid. Also, the nitrogen source in Osmocote is primarily ammoniacal...

Root rot? I don't see any root in the image. They look pretty good to me with the exception of the one brown leaf tip. That could be caused from many things. Are you having issues keeping it attached...

K2SO4 provides potassium. What many people fail to see at first is that KNO3 provides a significant amount as well. A standard EI dose for potassium is 7.5 ppm. KNO3 provides 4.73 ppm. This is...

You're comparing apples to oranges. TDS is total dissolved solids. KH and GH are measures of the amount of various molecules in water.

I do understand the differences the table show. My point was that we shouldn't ignore dry analysis based on this. Blabber worts are also a different animal in regards to most plants we keep.
