Outdoor Mold/Pests/Deficiency

What's up Growers. I'm growing some exotic red runtz from a buddy of mine. He gave me some good size clones back in July. No issues no bugs no mold. I was using Fox Farm nutrients and switch to Advanced. I live in Michigan and the weather has been questionable. So here they are and what I'm guessing is week 3 Outdoors and I've been fighting a constant battle against powdery mildew. I've seen a few bites as well, but not too worried because of the spiders, dragonflies and wasps that protect them. You can see in a picture where the leaves are turning pale and forming brown spots. I believe this is a Cal Mag deficiency and I'm already on it. I've been "growing" for about 14 years on and off. Any opinions or comments?

Welcome to RIU

I dont clearly see PM in the pictures. The spot on the leaf in picture 16305097102625817557371086160709.jpg
looks like the start of a septoria spot. I'm not sure what the discolored mottling is on that leaf.

Overall, it looks pretty healthy in the pics.

The only thing that grabs my attention right away is the size of the plant relative to the pot. You must be having to water/feed like every day. I wouldnt try to transplant now though.

What is your feed/water sched, ppm/ec, pH?

I've been fighting the PM since they got big in August. Theres a wooded area nearby and the train blows all the wind towards the plants. I started with Fox Farm Marine Cuisine.. which works great. Then used Tiger Bloom and Big Bloom and Fish Shit. Watered once to twice a week. Yea the big one likes to get watered often.. but now my buddy gave me some Advanced Nutes Sensi Bloom A and B with Big Bud and Bud Candy. Trying to slow down the feeding and ween them from Fox Farm. I have some Fox Fram pre mixed to feed them, but I just fed them Advanced this morning with some Cal-Mag to be safe. Haven't been using Cal-Mag since before flower so I'm thinking that's the yellowing I'm seeing. The PM is in image 1630.....6660

UPDATE! Mold is starting to go away, septoria leaf spots may be fly bites. Im using Mammoth Canncontrol for now, once the weather gets less humid I think I'll be good. Buds are growing very nicely. Red runtz is a tough strain but man does it smell good. Here's the nutes I'm using right now
