Mark I got my dehumidifier and had no idea how tiny they were.....I was thinking maybe 18 inches but it's alot smaller than that. I've already ordered a second.....

Actually I'm pretty happy w/my diagnosis. I think you are seeing normal yellowing of fan leaves during flower and because they are dying they are the ones most likely to get leaf spot.......which is what I think that is. Mark may have a point about the baking soda but I don't think that is something that will harm the healthy leaves....witness those nice buds. The weakest leaves are taking the brunt. I thought that was normal for a plant.

Mark did you say that puppy brought your humidity down 10%?
