I seem to be having the same problem with my girls. I had this problem with my first grow when using miracle grow ferts, but luckily was able to finish off my grow before the damage was fatal. I'm currently using FFOF and a whole different line of nutrients and i'm still having the same problem. I tried flushing with ph corrected water and such but still to no avail. I would try giving her a good flush at the least when using the miracle grow. I'm curious to find what the problem is myself. Goodluck! :hippy:
