I might want to call that a mag def. Do you supplement mag in any way?
PH is low... that will effect uptake of nutrients... like mag.
5.8 is generally the target PH for hydro.

Light mag but if you're in the final two weeks just flush it all out, you're already rid of much mag so you're ahead of the game!

Could be Mag could be Boron either or I suspect a deficiency. I would change water, run neutral for 24hrs then drain and run normal nutes according to time frame.

Looks like mag and/or potassium issues, often caused by PH not being stable in your medium. Also if the roots are too cold, it can cause an uptake issue.
