?

That could be one reason... to me.. it seems whole plant on the light green side.. with the burst of growth tops lightest.. seems you've been to easy on Nitrogen...

Hopefully other opinions to follow.....​

Seems like a lot of three finger leaves! Kind of looks reveggy. Have any lighting mishaps along the way? Probably doesn’t have anything to do with the color though.
