Milk Residue on Leaves After Treatment

So, I had some minor mold issues that seem to have subsided, but prior to the remission I sprayed my vegging plants with a recipe of dish soap, baking soda, milk and water. I've seen no negative effects from this however, I have residue from the mixture on all my leaves. Similar to water spots, but a bit more filmy.

I'm not concerned about the residue inviting toxic elements into my grow room, but I am concerned that such a film could interfere with photosynthesis. However, I'm no botanist.

Can someone who has used the milk/water spray shed some like on this for me? I'm a little bummed about the aesthetic of my plants right now, but if it isn't interfering with light absorption I don't really have a reason to complain.

This is my second grow, so thanks to everyone who made the first one successful enough to keep growing/learning.

I use 1/8 milk water ratio for PM control. It works well (it does prematurely redden hairs in flower), but yes it leaves a film. I hit mine with a little high pH water (which also keeps down pm) in between treatments to rinse them, but... don't let that water sit on them or your inviting more pm. Astetically I don't like the residue, and I'm sure it cloggs stomas. But... in the worst case id rather have some clogged stomas than pm. A wetting agent helps with the spots if added to the initial milk solution

The whole point of milk is to raise ph. No residue, no ph rise.

Sulfur burners, potassium bicarbonate, sodium bicarbonate all act by raising ph. Sulfur gets 100% coverage, doesn't add humidity and can be used until 48 hours before harvest. Ignore myths about flavor being ruined, just nonesense from ppl that don't use it.

Thanks for the input, if it's not the milk that has left the residue, perhaps it is the soap...either way, how about just spraying it with water?
It's just ugly looking. I don't want anymore spots...even if they are ok for the plants...

And yeah, clogged stomatas is what I'm thinking, but my knowledge is so basic I hate to even use words like stomata lol
