Help identify leaf deficiency

Hi there I have a auto cbd lemon potion at around 40 days sitting at 22 degrees 50% humidity in biobizz light mix. I've just started using biobizz grow and flower fertiliser at a week mix as per the chart, any ideas on what's up with my girl. The discolouration to to leaves seems to be apparent all the way up the plant. ?
She doesn't appear to have any growth issues and is nice and tall standing at 1m. Any help would be appreciated as I do not want to loose her to a silly deficiency.
Thank you

So you've got that weird variegation that happens...it's not a def and it'll go away as the plant grows...please don't think you did anything wrong and try to fix it...new growers especially are stumped when they see it. I'd be interested to know exactly why it happens but since it doesn't harm the plant I guess nobody's in a hurry to discover how it happens.

Leaf tattoos ... variegated leaf / mottling from chlorophyll density.

It happens.

Thanks for the reassurance guys, I'll let her be. To be honest with this grow I've been very cautious with everything, I allow them to completely dry out before watering and give under the amount for required ferts atleast this way its easier to establish control over what your doing.
Thanks again
