protekt is very concentrated.
only 1/2 tsp/gal provide 50ppm silicon (what plantys genrally prefer) - every watering.
if give too much to solution, can easily go over 7.0ph!...
also, 1/4 tsp/liter excellent foliar spray.
should notice woodier stem & thicker shoots. also increases cell wall strength &
should increase ph. good to add to solution last, then adjust ph...
found that ph 5.0-5.5 (input) provide best results w/ water soluble ferts (dry). keeps micro-nutrients (esp iron) in solution & avaialable to plantys. they seem prefer slightly acid environment. also, due to 90% nitrate content of h!dr0-tyoe n in ferts, ph rises once cec occurs... checking media & run-off against input ph-over 24-36hrs=...

so... usually adjust ph down - using ordinary distilled white vinegar.
good point about vinegar (dist white) is that it does not add any nutrients to the mix...
if make 5 gal of solution, 2-3 tsp distilled white vinegar capable dropping ph to 5.0 (ideal for lady gardener)...
...?...
curious why would desire ph-up?
what is the ph-target & why?
ej bloom also work for ph-down, very small amount.
