I have several plants that suffered from cold and subsequent root rot last April.
I trimmed the roots, dusted with cinnamon, repotted in smaller pots and the plants recovered.
However, now that the plants are getting new growth, the foliage is almost silver, the growth is slow and smaller than it should be. I suspected too much light
One plant is a red reverse and today I noticed the red reverse is almost silver!
Lack of Nitrogen!
I fertilized one small plant with a recommended amount of African Violet fertilizer and a dose of fish emulsion.
I added a few grains of 24-10-10. Not even a pinch in a quart of water.
That plant greened up.
The Red Revers turning pale under the same light and conditions as the other plants seems to be an indication of fertilizer.
The extra nitrogen is a One Time application.
I will continue using the African Violet food.
When something is wrong with violets, the possible cause is endless.
Now I know how to judge fertilizer amount by the condition of the plants!
