As you can see i had several probelm of nut burn, not sure why because the last grow there was no problem, anyway i flushed for 3 days and lowed nutrient concentration, photos are at the end of week and i can say they are really better then before, but jack herer still have massive burn, gonna flush her for a couple more days while feeding the other with lower nuts schedule; i hope everyone will survive to the end.
