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.

Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!

Burnt or K deficit? Or offended?
Please could you tell me what you think about the (burnt?) edges? My guess is that I should water more often to lower the concentration of nutes in the soil? Nutes are RQS pellets in the soil, watered with plain water every 10-12 days.. THX!! <3

Is my plant giving a warning
I'm not sure if I have a problem or it's normal. Some tips show damage I think it was the light to close so I moved it back over 12 inches away. I am giving the bloom every other day but half of the water i give. No nitrogen is being given,hardly any ever she doesn't like it.

Damaged leaf
The damage leaves from yesterday looking worst today. Someone of the experienced growers can define the problem? I Adjust the light to 25% and about 40cm high like suggested from @m0use. Is this a clear lightbun or can i be something else? Thank you very much :D

LEAVES AFTER FLUSH
When I flushed my plants all leaves went looking down as normal, but now that they dried they kept that shape and the tips that are really dry (due to previous overfert) are curling all weird...is it ever gonna go back to normal? Is it still good anyways?

Leaf diagnosis: nutrient burn or deficiency (or both)?
he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy
