The fertilizer solution chart (pdf) at Peaceful Valley is a good resource for water soluble organic fertilizers. There is a column for fertigation suitable fertilizers. They also have a good selection of water soluble organic fertilizers.

I installed Rainbird dripline in part because of the 120 mesh required which is more forgiving than other driplines I checked into. It also has a better (wider) pressure spec than some others.

I inject Vitamin C to neutralize chlorine. The reaction is almost instantaneous. I use a crystalline form available at Trader Joes. It is cheaper than tablets and dissolves very quickly. It doesn't take very much.

I installed a 140 mesh disc filter because disc is supposed to be better at removing organics than a sieve filter.

I haven't injected organics yet. The benefits of using the drip system based on the watering technique alone are notable. I have now started injecting synthetic fertilizer. My tomato plants have never looked better.
