If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

I seem to have some yellowing on fresh growth starting to occur. I'm not too sure how to prevent it. I have started to do some LST and find it to be successful and a lot of fresh sites have appeared and wonder if this could inhibit it by stressing the plant?

Vexatious yellowing I can't get to correct.
This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.
