If you dissolve the ferts in water, and use that in the "leaky" container for dosing, the incoming water will dilute the remaining water in the container, so the dosage per day will steadily drop asymptotically to zero. If you use solid ferts in the bottle.......????

If you put a rubber bladder inside the rigid bottle, with slightly pressurized air between the bladder and the inside of the bottle, the liquid ferts might be expelled at a near constant rate. And, if I were the son of Warren Buffett (in good standing) I could afford to use all ADA equipment.
