Looking at the charts I would guess nitrogen deficiency. I’m still learning though..

if this is happening more on the top of the plant it could be from light stress, you may need to dim your lights. more pictures and more info about your environment and grow style will help to diagnose the issue.

try Epsom salts. looks like mg deficiency to me.

Look the plant is yellow from lock out. What media are you growing in? I would prepare 1 gallon of water , pH’d to 6.5, then sit my plant in it until saturated. Let drain on its side. Then wait. Don’t do anything without taking time to check. Also you may need to recalibrate your pH pen.
