fertilizer-nutrients Vermiculite relation with under and over fertilizing?

Let say you have a soil mix with vermiculite mixed in. When there is water available the vermiculite hold on to it, when there is not, it releases it.

So when applying liquid fertilizer the vermiculite take on some of the nutrient. When the soil dries out, it releases it.

When there is frequent watering or rain there is no problem.

But what happens when there is a dry period?

Let say there is infrequent watering with fertilizer. Than the vermiculite hold on to the nutrients. When the water evaporates the nutrients are left behind.
When the next feeding has a higher concentration of fertilizer than whats in the vermiculite, osmoses sais its stays inside the vermiculite in stead of releasing it.
So the vermiculite might get more and more saturated with fertilizing.

Now there is a dry spell, with the nutrients "locked" inside the vermiculite and the plants start to show sings of under fertilizing.
At this point one tries to correct this by adding fertilizer. This in turn adds new nutrients and take the nutrients out of the vermiculite. The plant gets hit by much fertilizer and suffers in term.

Does this make any sense or am i thinking of this in the wrong way?

Vermiculite can hold onto cations (Na+, K+, ammonium, ... - Boss @The Hot Pepper , how to add super/subscript?). Preventing salt build-up begins with not adding more vermiculite to the mix than recommended (10 to 20%?), but if you are afraid there is too much salt in your soil, you can leach it out of the soil by applying copious amounts of water. Vermiculite works like a sponge: just as sponges have a max absorption capacity, there is also a maximum to the amount of nutrients/cations vermiculite can retain, so let us make the reasoning circular and fast-forward to the beginning >>> preventing salt build-up begins with not adding more vermiculite et cetera.

It sounds like way too much vermiculite to be causing serious swings in your soil like that. I would do as ahayastani says and just add less. If you have added too much and can't repot then flushing might just give you water logged soil with all the water retention.
I am probably talking total bs here but what about adding another cation in watering to lock the vermiculite? No idea what to use though.

looks i though of this the right way. This is a hypothetical topic, just for me to learn from.
