H3PO4= phosphoric acid
You can get this at hydroponics places as it's most often used in pH down.
Some hydroponics places use H2SO4 for pH down so as to keep the plants
growing vegetatively. Just ask they will know what your after.
Fischer Chemical supply has monobasic potassium phosphate. A jar will last a

I doubt you'll need to wait that long. Perhaps 3-5 days max. I would not add
the 40 mls at once. Dole it out over a few days. Add more as plant growth
increases. Folks always seem to freak to some degree when they have good
macro's/CO2 at how much trace you can add.

3-4 weeks is a good time to figure out if what your doing works or not.
Many rush after 2-3 days and assume something does or doesn't work.

Green hell:) I wait 1-3 days. Then add the PO4.
