This is a Northern Light Automatic plant. It is starting to show this leaf nutrient problem. The leafs that show deficiency are only the lower leafs. I have fed it water out of a 2L Bottle with 3,8ml canna vega, 2ml canna rhizotonic, 2,5 nl canna zym, 1ml Sensi Cal-Mag. Ph=6.1 EC=1.1. Can someone tell me a solution? (Sorry for grammar ik not EN)
