First ever grow. Clones, summer 2019

This is from a previous grow last summer but I wanted my grow online. I found it worked out surprisingly well overall for my first grow and loved the everyday care of them. Looking back after I have started a new grow, there is nothing huge that I would do much different; EXCEPT.... 1. Defoilation is a thing, lost a few buds to mold. 2. My buds did not tighten at all. I am not to the harvesting point of my second grow, so havnt done research, but this is a breakdown I had of what marked down that I did.... "To harvest, cut base, avoiding touching buds, hang upside down for 1 week at 18 degrees, 60% humidity. Huge fan leaves can be cut off. Constant slow airflow. Somewhere dark. If only top buds are mature, harvest them. Give another week or 2 for tiny buds to grow some, then harvest the rest. Dry enough when branches will be slightly elastic and bend, but when fully bent, will snap. (Took 10 days) Trim tiny fan leaves at base as much as possible until hidden from sight. Trim excess leave tips that do not have Crystals. You can trim more to make tighter buds, and collect the cuttings to smoke (harsh) or decarb and make butter. (I chose to leave everything that had crystals) Put all buds in a SEALED metal or glass container for ~3 weeks. Burp daily." Would anyone have any tips or advice as to why my buds are still looking like tumbleweed? Lol
