You have to take them out of that light if you want any answers that might even be close to legitimate.
There is no way anyone can diagnose your plants properly with the colors completely screwed.

mehhh

all leaves same this leaves pics. they are3 state. soft yellow first leaves second leaves some yellow colour third state leaves too much yellow.
what can i do is this nutrition problem

31 seems hot, but they are not showing signs of heat stress. She just looks a bit hungry. What is your feed schedule? Have you considered a tea? I have had similar problems, I gave a EWC tea with a little organic compost and it turned them around. Hard to tell for sure from those pics though. Try to get one of the entire plant out from under the HPS and under natural light if you can (I know it can be difficult to do sometimes).

maby nit lock out did u check ur ph tips burnt nit burn that yellowing looks like nit def .....so check the ph of ur soil i honestly wouldnt know thats what i would do

the water at the bottom ph: 6,6 and i feed she with flora nova grow 7-4-10 ec: 0,7 ph:6,1

i flush them with spirng water every 2 days because my dark room RH %25 too dry.. soil dry early.
my feed schedule for weekly:
pure spring water every 2 days : P
nutrition 1 per week : N
pass day: X
XXPXXPN

Looks like she needs some more, either a tea or maybe change to water/feed/water/feed or maybe just a top dressing to give a little boost. Nothing crazy
