What are these deficiencies

[Taktookato]

Hello guys,
I’m growing under 2 600 watts hps,
Everything has been going super good.
I’m growing rainbow wreck and wihite widows x big bud.
Been flowering for 20 day’s and I found these deficiencies on my plants
Can I know what they are deficient in
They look like different deficiencies

First one is just a light burn. Ignore it.
They're hungry. At 20 days you can water once with a veg fert to slow down the paling.
The pale leaves with brown down the center could be the following:
Leaf is in the dark, plant doesn't want it anymore
Plant is generally hungry and pulling nitrogen out of it
You could be running out of available calcium.

Verify your runoff pH is 6.5-6.8 if you're in a traditional soil mix to rule out souring.

Your leaves are how I'd want to see them 2 weeks before harvest. So depending how long your expected finish is, judge them that way.
