i only started using it in flower after your recomendations , & i stop everything but V&B by mid flower .... coco tends to hold onto certian nutes more than others & can build up a toxicity , especially Calcium . have read & been told many times that if your using calmag in coco , that by week 4 , drop the Cal & just add Mag if its needed .
you being in soil could probably go longer with it .
dans, does the calmag you are using have iron or any N in it? i had really bad reactions when using i think AN cal mag plus 4-0-0. it really burns my girls good in coco
