Your kidding, right?
What have you calibrated the gallon per square footage applied?
What percentage of Iron plus other additives are in these jugs?
Your question leaves way too much info hanging without you providing more info.

i see that you are new here... welecome! first are you certified in your state to spray lawns for (hopefully) profit?
next here's some notes how how to calibrate a sprayer.

What you need to do is calibrate your sprayer. Fill the sprayer with water only. Measure off a 1000 sq ft area (easy way 33ft by 33ft). Spray it with the water in the tank using the same pump pressure and travel speed you would use if doing it with the chemical.(Tip pull off enough hose to cover a typical yard when doing the small test) Refill the tank taking note of how much water was used. The amount of water used is the gallons per 1000 sq ft. Products are applied at a specific rate per 1000 sq ft or acre.

For example: if your test run resulted in your needing 3 gallons per 1000, a 400 gal tank will cover 133,000 sq ft per tank. So you need to add the amount of product (see label) indicated for the type of grass being treated. The correct way to apply chemicals to a lawn is not how many ounces per gallon. It is how much per 1000 sq ft or acre.

Letís say the product calls for 6 to 9 ounces per 1000 sq. ft.
That would be:

2 to 3 ounces per gallon of water
400 to 1200 ounces per tank (tip when getting a new tank we would fill it at metered hose to check the gallons. most 600 gal tanks would only hold approx 560 gallons for our fill standards)

Remember to do this several times a year we use to do bucket test every Tuesday.
Pull off enough hose to spray a yard.
Spray in to an empty 5 gal bucket for 30 seconds (times by 2)
This would give us our gallons per minute.
Our guys would cover approx 1000 sq ft a minute.

Read and follow the label always and be aware of stressful conditions in the lawn.
