Zuzu,

Have you seen Doctor Optimara yet? It allows you to narrow down the symptoms of your plant and think about solutins. Sometimes it is helpful, sometimes it can just confuse you more--but I learn a lot there.

I don't know exactly what you are seeing here, but I would say "feeding" is an issue. I noticed on one of your other posts that you had tried a stick fertilizer--did you try this on the violets that have these symptoms? Maybe too much fertilizer is the cause. Or, if these have received no fertilizer and need to be repotted, that would be a cause.

Here is a link that might be useful: Dr. Optimara Diagnosis

Hi:
Most yellowing of leaves on virtually any plant is due to either over-watering or under-feeding. I feed my violets with every watering. And if you are using the pre-packaged soil mix designed for violets, it drains very rapidly so it's hard to overwater them.

Keith, I'm sorry, but most commercial AV mixes are still mostly peat and too heavy. I stick to the 1:1:1 mix; it's never failed me.
