just as the schedule said, I ve flushed once before i posted this and gave them a dose of calmag when they dried out, I saw no change after about a week, and the browning rust spots and curling continues. So tonight I flushed again in hopes to cure this. I had a bout with heat for about 4 days straight at the beginning of their cycle and thought maybe that had something to do with it. I just put fresh rooted clones in the flower room 2 weeks ago and they are doing awesome no problems at all, so Im lost as to what it could be. Also i have a white russian fem seedling that is about 2 months old in veg and its starting the same thing, while the sour d mother that I just got as a clone 2 weeks ago from the dispense and its flourishing aaaaaaaaaaaarrrrrrrrrrrrrrrrrgggggg "Im at my whits end".
