Hi.
I have two sources of vermicompost, from my own worm tower, and also from a friends worm bin. One plant was filled with the compost I made, the second with the compost my friend made. The third plant I mixed the two composts. The fourth plant received no top dressing of any compost.
All three of the plants with the compost are now hit with zinc deficiency. The fourth plant is
My compost had been building and cooking 7 months, not sure the pH or its overall nutrient density/contents. I think the composts are causing the Zinc def. Mainly just based on that the three plants with compost are showing this, and the fourth is not.
It is for sure zinc, I have confirmed it from images and documented resources. I put a good flush of filtered water through the three plants, and will see if the extra water helps. The water did return yellowish/gold, and when I put the water in it was clear. From what I see, it extracted something out of the medium.
What I see as a good choice is to observe how the plants respond, and if improvements occur, continue to give them extra water until we are healthy. If not much improvements, remove the top dressings of the vermicompost, and continue to water.
Do you have an experience to share about top dressing a plant with compost and causing a deficiency?

You presented mostly rhetoric so any kind of thoughtful or "valuable" response is going to be limited. This mysterious yellow runoff with flushing is not that uncommon. On another note, an excess of P or Cu can antagonize the uptake of Zinc. Best wishes
