Yeah this is a great place to learn, and have a good time doing it. I know every bodies circumstances are different, but if time/space allow it, I say never give up. Even if it sucks, grow it out, and figure out what went wrong. Learn from it, but most of all, enjoy the experience.
Even on a not so good grow you can still utilize the plant. You could always make a tincture, edibles, extracts for dabs. I had 2-2" plants get pollinated by that damn pollen fairy, and they produced almost no buds, but where loaded with tricomes on the bud that was there. I made some shatter out of them, and stayed pretty stoned for 5 days. It wasn't the 4oz I hoped for, but for what I got it was great! Grats on the light bud!:smoking:
