Nematodes and Fertilizer

Hey there guys, I noticed aphids and fungus gnats last week in my garden and used nematodes to kill them. I've read that nematodes might have adverse reactions to the high nitrogen content in fertilizers, but I really need to feed since I'm in mid-flower. Flower ferts aren't high in nitrogen anyhow, but I'm not sure what to do. Anybody know a safe ppm to feed with nematodes? Or can I just call it a fix after a week of using nematodes and plain water?

If your fungus gnats and aphids are gone, I wouldn't worry about the nematodes. Use some soap to kill any survivors(gnats and aphids), you still need N during the flowering phase so don't skimp it just to keep the nematodes alive. Imo of course, im sure other farmers love beneficial bugs!
