I've been battling this issue for almost 3 months now and it keeps kicking my ass.
My plants look beautiful all through veg. Nice and green and happy, save for a couple random fan leaves that will die off.
Problems start when I move them into flowering. One by one, the fan leaves begin to shrivel up and die, starting toward the bottom of the stock and making their way up to the mid section. Once all the fan leaves are affected on the main stock, the fan leaves on the branches start to do the same thing, making their way out from the beginning of the branch and one by one, the fan leaves towards the end of the branch become affected.
I'm running a few different strains in a big room 20K watts in flower, co2 @ 1100 ppm, temp around 82 to 85, humidity ranges from 42 to 53%.
I checked some leaves with a 100x scope and DID found what I think are broad mites, but I haven't actually seen one move. Starting 10 days ago (when I first moved a new batch into flower), I treated with Avid, waited 3 days, then Forbid, waited 4 days, then Kontos. I've noticed the plants are still getting worse.
My last 3 batches had a terrible yield, with 80% of the fan leaves dying by the time I hit harvest. At the time, I was giving them a concoction of different nutes that a few friends use with great success, the past month I backed it all down to just 20 mL/gallon of CNS 17 Bloom and that's it.
This is a new grow room I just started in May and I've never experienced problems like this before. I'm in desparate need of help! Somebody please guide me!
Here's a couple pics
