Early on, too much phosphorus was given, but I'm wondering about calcium. Have you been using the calmag all along, or was this recent dose the only one you've given? The leaf death is complex with green, yellow, and brown colors in a fairly random pattern. Usually this indicates misusing fertilizer. The only way to know for sure would be to have the leaves analyzed but I don't think that's a good idea.
polishpollack Reviewed by polishpollack on . Is this Mag & Cal or ? deficiency? Hello... We're growing indoors in soil. Take a look at these photos. Does it look like a magnesium &/or calcium deficiency? The plants just started their 6th week in flower. We fertilize every other watering & pH is always around the mid 6's. PPM in our water is around 60. Day temp in the room is around 75. Thanks for your help. 289924289925289926289927289928 Rating: 5
