Calcium or Mg deficiency?

Calcium or Mg deficiency?
This is my straberry cogh at 3 week of vegetative, and i notice same days ago that the leaves were turning yellow, but a strange kind of yellow. so i look for answers and found that it could be magnesium deficiency.
Please look at the pics.
PS: look the bending, what do you guys think about is it doing well?

Yeah unless that is new growth I'd say that is most likley magnesium def. Pretty classic case, yellow leaf green veins. Maybe try adding some epsom salts to your mix.

Im with Banditt Epsom salts !
