Tangerine Dream [Barney's farm]

This is my first time growing sativa dominant strain and in 60/40 coco-soil mix. So far so good although we haven't avoided all problems, she is looking healthier by day. Some rust still there bur I figured it may be the air flow which was inadequite. I now have my ventilation fan on 24/7. No more rust appears to form or atleast very little. Update day 49 First few days of flowering behind and first pistils are visible. Update day 54 Decided to remove the scrog net since it wasn't helping and it was hard to tie her from behind. Now I was able to spread the branches nicely so she has room to grow and flourish.
