If my idea fails (gravity fed) this might be an option too http://www.reefkeeping.com/issues/sk...alkdripper.htm

Be careful with any type of automatic dosing system for plant ferts. Some of them can become separated when left in a container for a while. This is why on some of them you will find the manufacture has printed instructions on the bottle to shake the bottle before dosing. You really should not try to dose ferts that are like that. Just something to keep in mind and double check.
I wanted to use a extra dosing pump that I have on my planted tank so I would not have to worry about forgetting to add ferts, but decided against it as at least one of the ferts that I use needs to be shaken very well before dosing.If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

So far I got a prototype, pictures in am. The ferts I use require a mild mixing (metricide doesn't. For now I am thinking of using it for a few days (once I get a good flow). And then maybe use it when I won't be home. Made some major changes from this afternoon :)

As long as there are ferts in the tank, the plants will use them when the lights are on. So if you dose your tank at 6:00pm every night, they will use them until the lights go off, then start using them again when the lights come on in the morning. It's not like they will be filtered out. Dosing the tank on your work schedule is fine. I dose mine around 6:00pm, and the lights go off at 8:30pm. They come back on at 12:30pm the next day. I have densely planted tanks with CO2 and carpets. I have never had a problem dosing the tank after the lights have been on for more the 3/4 of the photoperiod for the day.
I think you might be overthinking the dosing. The plants will use the ferts when the lights are on. When the lights are off, the ferts will not go anywhere, and the plants will use them when the lights come back on.

First try, PB jar didn't seal well enough, and using a mason jar had to be the plan. Also, the gravity fed made a mess or didn't flow, was hit or miss
Switched to mason jar, have 1 air feed line, one liquid line
Use the air pump to pressurize the jar, forcing the liquid up and out
Still trying to calibrate it to slow enough, the plan I am thinking is to have this air pump on same timer as the lights, total of about 8 hours, so the goal is to get to about 1 drop per minute
Assuming 1 drop = 1/20th of a ml, I would get 3ml per hour and end up with the approximate amount of the ferts daily over the same 8 hours the lights are on.

I'm an engineer if you couldn't tell lol. 50-60 Euros = around $70 USD... that would be a bit much for what I'm looking. Heck, I might not even use this thing. But its more play around a develop something that works
If I end up doing my aquarium rack in the future I think something like this could be built with a manifold to dose multiple tanks, each with its own valve
