What a disaster! You need to simplify shit...alot. Take the carbon filter out of the tent. Put the fan on top of the carbon filter. Run one duct to the light and leave the other end of the light wide open with no ducting. Small tents it's the easiest way. You'll get MUCH more height in your tent for your light and better airflow from your fans.
Things looked good through veg, but you've got too much in that little space. Needed to trim the bottom 1/3 of foliage off of those plants for sure to allow for some airflow and flowered a little smaller. Your growing skills are getting there, but your setup could use a little improvement.
Haha, did you wrap your light in mylar or foil or something? Haha, I'm high and that shits got me rollin'.
