Not all brown leaves are "burned by chemistry." The leaves in the photos have magnesium deficiency. Advanced stage of leaf tissue death will always look brown and crispy, but determining the cause is the issue.
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
