Follow the link to a pic of my alternanthera reineckii that seems to be having some trouble. Anyone have any ideas? I dose bi-weekly with KNO3, fleet enema, and flourish. 2 watts per gallon and diy co2 and 50% water change weekly. Most everything in the tank is growing great. A. reineckii is growing a lot but most of the leaves look like the pic.

I'd say its K deficiency. Notice how it's the older leaves
and not the new ones. Stick a small peice of Jobes in the
root and see how it responds.

I've had glosso do a similar thing, it went green->yellow->tan with holes, I think its nitrogen in my case, whats the difference between nitrogen and K??

Plants use Potassium mostly as an ion to promote water circulation through the plant.

Nitrogen is used mostly as a food source to create the Amine Groups (NH) in proteins.

Potassium Nitrate is particularly useful because it provides the plant with the nutrient and the ion needed to absorb the water containing the Nitrogen.

Best,
Phil

What type of Jobes are you referring to? And how small is a small piece? Maybe a half inch cube? or smaller?
