hey there bluberry, was just wondering how your girls are doing, and if you ever found a solution to the spotting. Mine are doing great now, I just did as suggested and gave them calmag and that 100% did the trick. all the leaves that had spots still have spots but they are not spreading, and all new leaves are 100% green. They are forming nice buds already. Hope yours are comming along as well.
Best of luck.
