    Na roots are perfect i think its magnesium deficiency and abit of heat stress aswell

    I had a severe cal/mag issue with my WW. That might be a cal/mag and K def but I'm definitely leaning towards a K def.

    Or try organics and never think about pH or deficiencies again.

    :)

    Good luck
