lemon water mold spary ratio?

yo i was watching a video on youtube and saw this guy spraying lemon water on his plant to prevent mold. I was going to do this but how much lemon juice would i add for a gallon of water.

Im also curios about this...

i use 2 tablespoons lemon juice and 1 teaspoon apple cider vinegar per gallon, clove n cinnamon for bugs too.

I heard you can control your ph with lemon water and backing soda, pretty cool trick to save you some money.

You won't save too much if any money because you need a lot of lemons to change your water in any appreciable way and baking side will create a very salty environment in your root zone. Beware of bro' science, it can be dangerous.

I dont know about the lemmon water, most anti-mold sprays are bases, lemmons are acidic Yea im sure their is something else in the lemmons but It just does not sound right to me

Not to be a prick , but have any reports
