Actually, the pics are pretty good! The second picture, upper right hand corner, Hygrophila leaf shows the definite 'hook' of Ca deficiency, Same picture, the leaves look 'scorched' with interveinal chlorosis. Third picture, the Ludwigia has curled, deformed leaf development with leaf edges turning downward. Fourth picture same.
Will, I need a tank size for the dosing levels to be relevant.
