A half gallon of 70% isopropyl alcohol mixed with a half gallon of water and the other substances puts the alcohol concentration below 35% which will not harm the trichomes at all. I use it all the way through flowering and have zero negative effects.That interesting, I would have expected a half gallon of isopropyl to do some major damage to the trichomes. I use it for making hash.
When making iso hash oil the concentration should be in the high 90s%. That's a completely different ballgame.
At <35% the alcohol evaporates quickly leaving more of the dissolved potassium bicarbonate on the plant (instead of more dripping off) and as a bonus kills bugs that you don't want to use insecticides for later in flowering. I have also tank mixed spinosad and bt with it and had great results.
This is one of the pictures I use to illustrate that I've had no ill effects on my plants or their trichomes (it's also one of my favorite pictures from last year)

It was sprayed at least weekly it's entire life. And I had no issues with powdery mildew or bud rot and I had no problems with borers, leaf hoppers, aphids or anything else.
