UI’ve got some leaf symptoms in my outdoor ladies that I’m not sure about. I’m thinking it’s bugs and some fungus, like leaf spot/septoria. I’m hoping to get some confirmation and some treatment recommendations. We’re finally drying out here but my plants went through a very unusual rain event with HUGE amounts of rain for 2.5 weeks. The temps are ranging from lows in the lower 70°’s and highs from 82°-87°. They’re various autoflowering strains ranging in age from 42-55 days old and are in 10 gallon grow bags with a mixture of amended FF soils. I’ve been feeding the FF Bloom Trio nutes but started feeding Mega Crop, Bud Explosion and Sweet Candy today. I’ve been occasionally treating with Serenade, spinosad soap and Neem oil throughout the grow.
The wet weather and the warming fall sunshine have brought out a SWARM of “army worms” (order: Lepidoptera) that are covering the property. It’s typical at this time of year but they’re awful and cause huge crop damage! When I saw the first one, 2 days ago, I started spraying BT. More on the plants today so I sprayed again. So, they’re certainly contributing to my issues; but they’re not the only problem. I have checked the leaves (both sides) with a loupe and I can’t find ANY bugs crawling but there are some (few) unmoving little things that look like microscopic grains of rice on the underside; and many of the fan leaves have these TINY white specks on the top side - not huge numbers or in patches but the ARE there.
I’m getting these little white/tan spots/specks, surrounded by a brown ring on the fan leaves as you can see in the picture below. In addition, there’s some patchy yellowing going on; but the yellowing is pretty much limited to some older fan leaves and a few down low to the ground and near the main stem. Finally, there’s some necrosis starting on these yellowing leaves. I’m thinking it’s Septoria/yellow spot fungus and either army worm bites or grasshopper bites? Treatment: a copper based fungicide drench and continue with Serenade spray and continue BT, Neem oil and spinosad soap for critters?
2 other plants have developed this strange pattern. They’re packing on the flower but I can’t figure out what’s causing this or what to do. It’s not everywhere but there’ll be 3 leaves here and two over there and another couple on another part of the plant. One of these girls is my oldest -55 days - and is really packing on the buds. I don’t think this is part of the natural progression of things. Any idea what’scausing this and what to treat it with??
Im planning to get some Grandevo (chromobacterium subtsugae strain PRAA4-1T) and some PFR-97 (20% WDG isaria fumosorosea Apopka) but I need to save up for it. They’re amazing products, from all my research, and they’re a totally organic approach to pests but it’s, in NO way, cheap. Lol! It’s damn expensive stuff. Here’s a terrific video (that I have a lot of faith in) covering organic methods of controlling pests: https://youtu.be/T33kgEnoydo
So, for the time being I need suggestions that are in the normal price range. Whatchy’all got got for me?? Sure could use some help!
