Hi , I've got a bad case of the ugly going on. I'm currently growing 3 photoperiod strains and my Humboldt seeds blueberry muffins are pretty sick girls. I popped 2 muffin seeds and they are both sick. I'm growing in Coco coir PH'd to 5.7 to 6.0. I'm using Mega crop 1 part nutrient. I'm following a pretty generic feed schedual that I've been using for a few years. My problem seems to target the blueberry muffins specifically. I'm leaning towards a fungal or disease problem, but maybe I have some fussy feeders on my hands. I would really appreciate some experienced eyes having a look at these and sharing your thoughts. I should mention I have a gnat problem that I've been fighting for months with Mosquito dunks and neematodes. Not sure if those lil buggers could do this but I figure it's worth a mention. I also should mention these are grown out clones, the mothers had the same issues and I thought I would scrap them as the grew to large and I didn't want to flower sick plants.
