I don't think its a oroblem with the plant. Necaude when you remove it a clear liquid slowly comes out.
Hmmm, I wonder if you have bugs? Spider mites? Do your leaves have little whitish spots on them?

I know but your problems comes from excess nutrients in the soils. And just watering it with water may help, but adding enzymes will help transforme the "sugar" in the soil so the plant can absorbe it correctly. Enzymes transforme organic matter into food for the plant, to make it simple. Less work for the plant
Can you point me to any documentation that provided that information?

Forgot to tell you Ro water or distilled water is the water you want to use .Most people use Ro .... Dont use municipal water it kills the enzymes( because of chlorine) and if you have well water (hard water) it's full of contaminants mostly limescale........!So it's not good for the plant. People who use that kind of water tend to get brown leaves ,ph issues and diseases ..........
You need to prove it, as I have stated many times that RO is bad water to use and tap water provides the best source of water and micronutrients. Sure some muni's have bad water...they have to make the water quality reports avail to public, so find out. RO/distilled has nothing but water and no micronutrients, and will cause yellowing, browning, scrawny growth. You have scientific proof to prove me wrong please post it, but many others have now tried getting off the RO and onto tap water and find they are doing much better.

That being said, I don't know the product you speak of, but my tops are as big around as my wrist on a 2 foot plant, what are yours like on a 2 footer?
