I'm guessing it's leaf septoria, but I am not sure if it's from deficiency or anything. It's spreading pretty fast, I had White powdery mildew on these before, but recently it's gone away, while the yellow leaves have arrived. Please help me cannabis family! Thank you guys!

The roots look fine. I think the ph is off, but I am not sure how off it is. when I use 6.5ph water, the runoff is around 5.9. So what would the ph of the soil actually be?

Hmmmm...have you recently increased, decreased, or added new nutrients? What kind of soil are you using? What wattage is your LED and how close do you keep it? Including this kind of info will encourage our veteran members to help out.

Unless you are growing in a swamp your problem is not septoria.It seems to be easy to blame it for every grow problem,you need to give more info about your grow.

The pH of your medium is off by the looks of things.

I made a post about corrective feeds:

Medium pH Correction (Soil and Coco)

Checking and adjusting the pH of your root zone in soil or coco is a very important part of growing healthy plants. Often you will notice nutrient deficiencies despite the fact you know you have provided an ample feed at an appropriate pH level. When this happens it’s generally either...

IMO, the first thing to confirm is your ph. Are you adjusting your ph after adding all nutrients and supplements? If your water is 6.5 before adding nutrients, it's probably quite low after adding all your nutes. You can buy a Blue Lab PH meter that will measure soil ph or liquid ph.

This is either a deficiency or burn. what's your ppm or ec of the nutes your using? Looks like the pistils are damaged from a foilar spray. What did you use to get rid of the PM? tbh you should probably scrap this grow and clean your tent completely and start fresh imho
