A pH of 4.8 is much to low for a soil grow. That tells us something. Too much fert. Even using the ferts you have without using the additional P ferts, I suspect might be too much. I didn't think it was overfert initially because usually overfert shows leaf tips turning yellow, then brown, then the rest of the leaf turns yellow and brown. You have those colors, but you also have areas that stayed green. This was a good one, however, because people can learn from this. I wonder if you water with some pH up, if that might make a difference.
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
