unlike common perception, your contorl over such things is severely limited. well-balanced diet and near-max DLI is all you can do. products taht promist bigger buds are simply lying. read the ingredients. these "special" products are made with ubiquitous things that are found in all fertilizer, anywhere, everywhere.... there's nothing special about it. also, boosting p/k blindly is not wise, which is another common belief. too much is simply too much. and giving too much is a net-negative. there's a "right" amount and it is relative to other nuts fed, pH, VPD, light .. nearly all environmental factors.... while there may be more than one ratio of nutes that technically work, some are more optimal than others. it's messy and complicated. nothing a person can resolve growing a handful of plants. people that feel confident about such things are just engaging in masturbation.

yeah, wait for the pistils to start to coil up. shouldn't be long. can always harvest the top colas first and let the lowers ripen more, too, if there is any deviation in development top-to-bottom, which generalyl is the case. that way you don't have too early lower or too ambered up tops. trichomes pistils density of colas. - use this one sparingly when the others point toward immediate harvest. no reason to fondle the plant more than necessary. use more than 1 metric. you'll moer consistently choose the same point in ripening process. some strains won't show amber much at all even if you let it die on the stem.
