Serenade not working anymore, harvest early?

Alright, so I'm about 6 weeks into flower on an 8-9 week plant (this is my confirmed flowering time for this strain). I have four "purple kush" clones that I highly doubt are pk. These days every strain is pk to somebody...

Anyhow, the clones came with powdery mildew (for free!), and have been applying serenade all through flowering and having success keeping it at bay. Now that the buds are deep and full of nooks, the pow pow seems to have no problem hiding, even amongst thick trichs!

Many of my buds are untouched. I was thinking of pulling the two that are most affected by PM. They are just about to pack on weight, but they are still frosty with fat bloated gland heads (showing the beginnings of cloudiness inside).

I don't normally, but I was thinking of pulling their big leaves off tonight (to increase air flow around buds), and chopping them down in the morning.

Any thoughts? It's a doozy, and I'm glad I have a support network...

sorry bro, ya start picking off leaves. u might not want to smoke it. could get u sick maybe not now but later in life.
theres a product called eagle 20. no mold ever for sure.

Nah man, no sickness. Serenade breaks down well before the drying process is finished. People spray it on tobacco as it cures. In any case, thanks for the input. Imma get started after this beer and a couple more posts
