nice plant but why are you touching the buds? oils from your hands can cause molds to grow ! i noticed some of the leaves are cut? the fan leaves provide all the most of the nutreints for bud production. still a good lookin plant.
18 years? 4 oz ? you can prune it and, top it to get a busher plant. i had my plant trimmed real young and it has like three identical plants growing of the main stem. the yield is going to be tremendous.
