General comments:
-Too much amending makes the pot a compost pile. Different organisms thrive in each different environment.
-Assuming soil is properly constructed, if the soil simply cannot keep up, it implies the amendments are not composted and available for the plant.
-A tea is appropriate for instant feeding in organics. I prefer a simple compost wash, but teas are all the rage these days.
Specific comments
If your issue is soil with accumulating amendments that have not composted properly, it means the life in your soil is not active enough.
It is not keeping up with the plants needs.
A Compost wash carries all the organisms necessary to boost activity in the soil and get nutrient flows restarted in the soil food web.
Some bacteria only live an hour or so, and successive generations can accumulate in hours if the conditions are right.
A balance between fungal life and bacterial life is also crucial in stuttering plants, the Glomus species of fungus expands the effectiveness of the root system, and provides nutrients directly from bacterial sources to the plant.
In addition to the compost wash, I would make a tea with a fungal supplement containing the widest spread of fungal spores and bacteria I could find. (I use Blue Planet nutrients Rhizo mix because I have some on hand)
This should begin acting almost immediately, and in a day or so results should be visible.
However.....
if there is a pile of amendments on the surface, they will now begin composting, and slight tip burning might be seen.
Depending upon how many amendments are left to compost, will decide how long you see tip burn.
In the future, compost the pot of soil for a month before use, by applying a tea and fungal supplement and keep pot moist.
