Light burn or nutrient burn. Could also be a deficiency as your plant looks really light green

Yellow/burned tips & curled leavesI 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.

should I be worried?I have a problem identifying the cause.I notice that the lower leaves become dry, crunchy lose their color. But only the very last leaves at the bottom. I do not notice any problem towards the apex.
Does anyone have a lead please? An excess of P ?or K?

brown tips on some leavesfirst week of flower, only one plant out of five affected, only couple of leaves close to the top affected (up to 5 in total) - my assumption is 1. too close to light (I have 40cm between 400HPS which seems enough), PH problem or deficiency (potassium?)

leaves tipsWeek 6. First pic.
She has preflowers and started the stretch period.
All new leaves have pale tips, just the new ones on each branch.
I'm using atami Terra leaves, 4ml/l 850 ppm pH 6.2
Is it too much? They don't look burned is more a deficiency maybe
