I have a 4200 psi, 4gpm pressure washing. Can u downstream 12.5, is the dillution good enuff and will it hurt plants?
Yes you can downstream it. Is the dilution good enough? Depends on what you are cleaning. For vinyl siding, most people mix either 2 gallons of SH and 3 gallons of water, or 3 gallons SH and 2 gallons of water. Pick a mix, and see how fast the mold goes away. Instantly, too hot… after 5 minutes, about right. Of course that’s up to you how fast you want it to work.
Just dont spray a whole bucket on a bush or anything, and you should be fine… water them down a little before hand if you want, and after. Dont have to get crazy with the watering, but use your own judgement based on how much is getting on them, and how hot your mix is.

It’s frustrating when guys with no knowledge or working capital clog up this forum with extremely base line questions.
