Shit don't feel bad bro, my first grow was one plant grown straight up like a Xmas tree. Yielded 58gram wet 20.7 dry. I fucked up a lot and learned a lot. Cured for three weeks n smoked it. Wasn't bad.
If it tastes really bad you may have cut it down early. You need to get a humidifier or somthing to get the humidity up and keep the RH at around 65% otherwise the plant will dry in two days or less ( bad for taste ) (real bad) then watch the RH and keep her where she needs to be for around seven days and then jar it and burp it. Good luck and congrats on gettin some smoke bro
I don't think I cut It down too early almost all pistils were red and in trichomes were good too I watered with florakleen for 2 weeks right now there in a tent with around 50-55 percent humidity temps 65-72
