Hydrogen peroxide 3% for pm

so i got this hydrogen peroxide 3% from walgreens..
Im having some pm issues ..
So would i have to dilute or can i apply straight without diluting ?

Straight.

Honestly it's not the best solution IMO. Often there is residual moisture after the H2O2 has broken down.

Probably best off with a potassium silicate solution that raises the pH of the leaves.

A sulfur vaporizer is the ultimate fix but you can't use it in flower unless you like buds that taste like cat farts. Also not good for tiny spaces like tents.

Honestly PM is a real battle, once it's established it's very hard to fight and typically likes to really start kicking ass in the last few weeks of flower.
