not sure when I can cut and dry these top buds? went into flowering stage on 5/22 so it has been about 2 months flowering. Planted seed 3/20. Autoflower and pretty much stopped growing vertical. was on vacation for about 12 days and not further growth since I left. I know they need to go dark for about 2 days from what I have been reading. when do I stop watering before clipping? thanks. 1st time grower, love the blog aspect of your site.
