That could be rootzone. if you are not allowing substrate to dry, do so in future. Also scope underneath leaves for any pests. spots related to deficiency are usually rusty-colored or yellow.

What is that?
Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6 Increased light intensity to PPFD 600. This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick. If it's a light burn, why not on upper leaves?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Weird leave discolouration
Not sure what this weird discolouration is from. I panicked and cut the bud off in case it was a disease or something. No other places on the plant have similar thing happening. Any ideas?

Waters
I still can’t determine whether this is a heat related or Nute burn issue. Is it that temps are too high causing a Nute problem? I’ve done all I can to lower temps.

Plant issue
Best guess as to what this is caused by? Only appears on upper half of the plant. Lower half is healthy and normal. Flushed with 5 Liters of 6.4 pH water stopped the progression

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

Grower question
Any ideas what the issue could be? Few weeks into flower. Dealing with fungus gnats and have kept the population very low. Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED). I have adequate air flow.
