Blueberry Cheese

I have done few times Kyle Kushman's Chiropractic training method. I think im having little bit nutrient burn so i reduced base nutrients by 1ml/l and leaves are little bit darker than usually. Leave tips from bigger plant have little bit yellowing or something like that and im having red stems even im using cal-mag. Im only using gardening ties to give lower leaves more light because i don't have scrog net. Few pistils now started to turn darker.
