Not septoria but burning from severe nitrogen toxicity would be my diagnosis. Feeding too much or too often (or both). Not watering to run off each time can accelerate the problem.

Problems
At the tips of the leaves, there are "claws" and discoloration between the veins.. Light, chemical burn, or a deficiency of some element?

Deficiency or Overthinking?
Wondering if this is some sort of deficiency or maybe I’m overthinking? I know I overwater sometimes and I’m trying to get that under control however my other plant doesn’t look like this it’s more solid green. Temp is at 75 daily and humidity is 35-40%.

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

Yellowing and Reddening of older fan leaves
I’m experiencing a lot of yellowing that progresses into dark red blotches. I suspected a possible cal mag deficiency but after upping the dose multiple times I’m still having issues. Any recommendations on possible causes/treatments? Temp stays between 74-76, humidity around 60%

Yellow lower leaves
Hi! I went out for the weekend and when i came back most of my plants had yellow lower leaves. The weekend has been very very hot and im wondering if it was lack of watering or is it a lack of nitrogen? Some in one plant the leaves were dead.

Plant seems to be dying, should I flush? And if so, any tips?
Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.

The week before flowering, I flushed the pots and brought the tds to 700ppm. Don't you think the leaves are dull? I feel there is a problem??
