I live in Phoenix and have a desert landscape garden.  I use a fertigation tank in line with my drip irrigation system to minimize fertilizer waste.  I am having trouble locating a retailer of water soluble dry fertilizer for the tank.  I used to use EZ Gro fertilizer which is difficult to find.  Do you have any suggestions regarding water soluble fertilizer.  I irrigate with 3000 gal 2-3 x weekly in the summer.  The fertigator can dilute a concentrated solution anywhere from 1:400 to 1:1600 dilution.  Any suggestions? Can another type of fertilizer be used in this system.  I think the formulation is slightly acidic to keep the nutients in solution, minimize drip nozzle plugging and also lowers the ph of the soil down a bit for our high alkaline soil.

Thanks
Ivan
