You would need peristaltic pump or some other positive displacement pump since gravity feed is highly error prone.
I've used peristaltic (metering) pumps in my designs for work before. I did some brainstorming on this. I'd need to have a pressure switch to activate the pump only when the sprayer pump is running, and it would be beneficial to have some sort of potentiometer to control the speed of the injector pump to dial my ratios in. It could work, but is quite involved. I'll keep that idea just in case I can't find a mixing valve that works for my situation.
There are two major hurdles to using a mixing valve or venturi. One is I have a low flow. The other is I have the same pressure on both sides of the mixing valve. Some mixing valves require a pressure differential, or they create their own pressure differential. I'll have to experiment with the ideas here and come up with a solution (pun intended).
