1 week before harvest purple wreck

Just want to know if sparying high ph(8.5) h20 on plants last week flowering will lessen or damage thc? I sometimes get powder mildew usually just a spec or two on some fan leaves but sometimes my shiva and my purple wreck get a little bit(very minimal) on some of buds,, I have been battling pm and have it pretty well handled. My room has great air movement extra fans and dehumidifier. Room humidity never gets above 40% and is usually at 35% gets as low as 29%. I also use neem, and serenade until 3-4weeks flowering

So back to my question is i have used high ph h2O and noticed it would visually eleminate it, my only cocern does it lesson or damage thc in last week of flowering?

no response ,, hmmmm ,,, anyone anything ???,,,,

It could make your smoke a little harsh, but as far as hurting or helping ????????

dude dont be spraying shit on your buds at all. if you want to kill or prevent powder mildew get a sulfur vaporizer and burn sulfer in your room with the lights off. i burn every crop it keeps them healthy

what he said, forget the fix, cure the initial problem amigo. Any spraying has the potential to damage yer buds right now

gotcha thx for response ,,, i 'll have to make sum changes because im runing all different weeks in same room ,,
