Hey guys! Coming into week 6 flower on my gals today and I need some advice. For the past week I have been battling what seems to be a serious calmag def, but I wanted some second opinions. It showed up light at first and by the next day the rusting was Heavy as it shows in pics. I inspected leaves for bugs and have found nothing, but like I said it's only this plant, my other 3 are textbook! This plant grew so rapidly I am assuming she got hungry. What do you think?? Thanks you guys! Lower leaves seem to be fine btw and I included pictures of my other plants so you can see what I mean, it's only the one!!
