Thanks for the great input everyone....
Another question about how to get the PH down. Is it necessary to inject your acid via a second injector, or can you combine your fertilizer and acid in a single tank and inject it all together. I can see there would be better control using two systems, but if you spent the time to dial it in, is there any potential conflict in acidifying your fertilizer mix.
Also, in an email correspondence with a "successful" it was suggested to add elemental sulfer at an example rate of 2% (I think it is %... the example 10-10-10-2 is how it was valued). which "approximates 8-10% sulfuric acid by volume"
It sounds like a lot of tinkering is in order to really dial in a good combination of PH and NPK. ....
And what about supplementing micronutrients? Is there a prepackaged solution.... what about Iron.... Iron sulfate vs.
chelated iron.
I have decided that all of this seems to be of interest to many here and that it will be a great subject to have a round table discussion on at the Agave Summit II....
