Whey as foliar spray ingredient

I' ve been trying whey as an ingredient for foliar sprays. Mainly becouse of its pH (3.6) wich helps to get mybmixture to the ideal pH to absorve nutrients (5.2). I also been adding things like compost extract and some salts like magnesium (small doses of 5 grams per litter) sulfate becouse of leaf discolorig pattern indicating deficiency. Whey is very cheap in my area.


Ive had mixed results in several corn fields and was was wondering if whey can be detrimental in some unexpected way. Anybpdy have experience with it or know of any substance within whey that could cause harm?

Also, my equipment smells like thinner the next day after usig a nixture that contains whey.

Thank you in advance

Hi Triato,
I know that milk as a foliar spray has been used to help with powdery mildew. I would guess that whey by itself might also help with something like that?

The smell... I have no idea other than maybe it is starting to spoil and just happens to smell that way?
