My tissue test shows that my plants are deficient in Iron at 55 ppm. I have some biomin iron that I was going to foliar feed but I have recently sprayed copper. Does anyone have experience with running ferrous sulfate through an irrigation system? I use a Dosatron like Russ Pugh has in his videos (only mine is better). Any other suggestions on raising my Iron would be great.

4 tsp's of the biomin iron twice a week per 2 gallon spray should do the job.
Pugh's dosatron is better because its a little cleaner.

I have run just about every thing through my drip tape. As long as it can be dissolved it should be no problem.

Wait a few days for the copper to become absorbed, or flush through with clean water, then spray with iron. If it's low in the leaves then you're not going to get it via the roots unless you don't have much in the soil or high soil pH or competing cations etc. So you need to spray, remember to adjust the spray pH accordingly:
