Diagnosis? Is this nute burn or nitrogen toxicity?

Slight burn. You're feeding MORE than the manufacturer recommends and manufacturer recommendations are notoriously over what your plant wants. Dial it back a bit, see where 4mL/L takes you after doing a water only feed or two.

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.

Leaf issue in Wk 6
Hi I am having a leaf issue late in week 6. It’s been coming on a while. I’m wondering if the ph is out or too high ppm. 7 gal pots in a Scrog, it’s hard to test runoff. I’m starting to flush now so does it matter as much as long as ph is good? More wondering for next run. Thanks

The leaves are wierd shaped, but growing fast
Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.
I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?

Discoloration and burnt edges on leaves
Can someone please help me diagnose this problem? At first I thought it was root dry spots from the drip watering system but it’s gotten worse. The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves. Anything helps, thanks!

I have black spots and burnt edges on a couple leaves. Some of the leaves are also curling down which I'm guessing is too much nutrients.
