Adding Phosphate to substrate

I have a 10gallon of mostly root feeders (crypts, hair grass, dwarf sag) I am seeing some GSA and thinking it might be because of low phosphates.
I have a few O+ caps in the substrate, plus a homebrew formula with worm castings, iron, and peat.

How can I safely add phosphate for these plants? I am keeping Neo shrimp.

Buy some dry form phosphate ferts and dose as required to maintain 1-2 ppm.

So you think I would get leaf uptake of phosphate with these root feeding plants? Or would I put the P in a gel cap and insert it into the substrate?
