My only suggestion for WPM, is to maintain air flow, monitor Relative Humidity, and apply hydrogen peroxide regularly (about every few days) before lights out. Neem oil is effective for a short period of time as well, but not recommended for use in flowering.
I have not found something that I’ve used that prevents it, but I’ve read some fungicides do. I haven’t tried any of those yet.
Anyway, I had to start dosing pH UP, as the nutes were drifting down (not up anymore)… but it’s been steady without any dosing for 24h. I think everyone had recovered from the silicon adventure. My nerves are still a bit shot though.
I trimmed a bunch of lower fan leaves that seemed to have WPM on them. I also had to adjust the net pot — it had gone off-center a bit and looked like it might fall in to the bucket. That’d be bad.
I would defoliate some of the larger leaves, especially if it’s blocking flower sites. Some of the under canopy could be cleaned up.
Looking good for sure though, above comments were directed to keep the larf down. It’s not fun to trim.
Use the back of your hand. Heat usually isn’t a problem with diodes, but it is a good rule of thumb. If you can’t take the heat, your plant won’t fair any better.
Today’s pictures. Finally looking like a plant in flower
pH definitely continues to drift down. I checked the pH up solution at lights out and lights on, and there was a fair bit of pH up adjustment overnight.
