First …. Zero need to feed every other watering. That is a sure fire way to overnuting the medium and plant.
‘Most feeding will last at least a week as it becomes available to plant. it’s a waste of product.
Second …. Stop slurry testing and trying to gauge runoff … tail chasing.
‘As long as your water and or feed mix is ph’d to the plant as needed then all is good.
Third …. Clip off all “ suspect “ leaf. See if issue returns and or becomes systemic.
‘There are plenty of “ garden safe “ fungicides out there for preventative use.
Fourth …. STOP WATERING EVERY OTHER DAY.
Wouldn’t doubt the excess moisture isn’t contributing to possible fungal issues.
First point. Only reason I'm doing that is because this soil I'm currently using drains very slow. I'm watering once every 5-6 days now so I'm feeding roughly once every 10-12 days. I probably should have specified that
Second point. I have still had issues where I properly pH water and it runs off a different pH than it went in. In most cases it is as you say though. However, making a slurry/checking run off is pretty quick and helps me checkmark some boxes so I can move on to other things.
Third point. Yea this is why I wanted the second opinion on if it was leaf septoria. If it's simply bug damage or nute deficiency then cutting the fan leaves off would be unneccessarily hurting the plants growth. Although, it might not be a bad idea to cut em off anyways and see what happens, especially this far along in veg where it wouldn't be the end of the world to cut the few problem leaves off.
Fourth... I stated in my initial thread that its new soil I haven't used before and it drains slowly. I was watering once ever 3-4 days, and the plant showed clear signs of overwatering, so I fixed it. However if it is leaf septoria, you are definitely correct that this heavy moisture environment is what allowed it to cultivate
