I saw that bot stuff you mentioned, but I think I saw it on another thread. Must have hit a bunch of 'em and the mod's got rid of 'em.
If you're growing often, you may want to consider getting one of those hand-held microscopes with a light on it. If I went by "how it looks" 9 out of 10 times I would have harvested weeks too soon and missed out on my buds getting even fatter. Impatience does sway how we look at our plants when figuring out when to harvest.
