what would you recommend? I have sf nematodes in the fridge
I have a bottle pf "Green clean" here on my desk, like a little nuke, if I need one. I spray "Purecrop1", sprinkle neem seed meal on the top of the soil, and have nematodes and killer mites. You need to figure what the bugs are, but leaf sprays are good to have around anyways.
Mildew & Mites.

just gonna throw mildew at me and mic drop? ive seen powdery mildew before never seen it look like that before. need to get these girls in flower already way behind waiting for soil so time is of the essence. I'm 90ish percent sure its thrips and I know how to handle that but the mildew Im not sure what to do about

oh didnt even see that you added mites to the mildew. why troll the infirmary with at best mediocre observations and then offer no reason or advice to what you claim or maybe even helpful advice? good on ya cant imagine what great insight your 1100 other posts contain

anyone? been reading all day still can't nail down one insect.or disease
I thought his reply quite stout. I kinda like that it wasn't long winded and that he took his time to help you.
Insecticide and fungicide. Fungicide is always a difficult choice, but various oil emulsions could make a dunking solution to tip the plant upside-down in.
Predators would mean knowing the bug involved. You could just send in a battalion of sandwiches if you get that wrong. They never seem to quite work either. Control, but not eradication.

Hi,
Basically it is this:
1. Mildew because of the necrotic patches and the infected leaf.
2. Mites because of leaves are damaged because something has been eating the edge of the leaf, yet no insects are clearly visible. That points to mites. Thrips make very small scratchy marks on the leaf.
I'll bet that under a microscope you'd see a lot of mites tracking around mildew spores and strands.
The good thing is that they're not in flower, so I would recommend pruning them for extra airflow and removing some of the mites physically. And use a good insecticide, preferrably organic.
You can make one from 1 quart of tapwater, 10 drops of pyrethrin (derived from chrysanthemums), a quarter teaspoon of vegetable oil and just enough liquid dishwashing detergent to dissolve the vegetable oil in water. The soap will dessicate any soft bodied insects (like aphids), the vegetable oil will smother them and any eggs, the pyrethrin will paralyze their nervous systems and the water will flush them off the leaves.
Any sprayer or watering can should be completely clean or new. That is the most important thing, because if there is anything in the sprayer, it is very easy to kill the plant, instantly undoing months of work. Also, just because pyrethrin is made from chrysanthemums and is allowed in organic agriculture, doesn't mean you should get any on of it on you. You should at least put something over your clothes to remove after spraying, and wash your face and hands with cold water after you use it. Warm water opens the pores of your skin. With those caveats, it's safe to use.
Outdoors that would be different. Giving the bugs enough other things to eat (compost, mulch, plants that produce nectar) reduces pressure on the plants. Predators are naturally attracted to large numbers of insects and nectar producing plants, so wasps, hover flies, etc. automatically fly in.
