Give her a good feed👍

It certainly could be a nitrogen deficiency ... but why no diary? Is this an autoflower you're growing? Photoperiod? We need the information a diary would contain so that our advice can be less of a guess... Please start one! Good luck

yup, for me it just looks like she's hungry, give her some more biogrow, and she should be fine .. she looks healthy besides the light green 👌
