  1. So my leaves are dying off pretty quick. I'm pretty sure it's one or the other the crazy thing is I'm growing 7 different strains and it's my blue cookies showing this the most. There is some similiar spots on some of the other leaves on other strains but it isn't as bad as my cookies. What do you guys think? The last pic is a different plant the first 2 are the blue cookies that's getting it the worse
