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.

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

Light or nutrient burn?
Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

Triple question: -Why are bottom leaves yellowing this early? -Explain 'What is this!?' picture -Is it normal that when they transition to flowering stage leaves' stems curl down like in Day 56, Rebel (II)?

Leaf Yellowing?
What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?

Dying leaves
I had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Is she too far gone or can she come back?
Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.
