What are the signs that she’s ready for harvest ...

Since you don't have a magnifying glass, advising you to use a 60X microscope is pointless, as I would presume you don't have one of those either! Judging maturity by trichome colour alone is not my preferred method, as some strains will never have amber trichomes and others will have 50% amber trichomes at 4 weeks of flowering, some 4-8 weeks before harvest maturity. I prefer to judge the health and age of maturity by using pistil colour as the guiding principle, the pistil condition will accurately define at what exact stage of maturity and the health of the plant is at, for it is these two things which determine trichome composition, health and maturity. If you prefer a more psychoactive and mentally stimulating high, harvest at around 5-10% of whitish pistils remaining. If you prefer a heavy, sleepy and lethargic couchlock type of stone, wait until all pistils have browned off. Be aware though, by waiting until all pistils are brown, this will result in flowers with reduced THC content and with enhanced CBD and CBN levels, which are the 2 cannabinoids that produce the sleepy/lazy effect. Harvesting with a few remaining white pistils are present, will give you flowers with their highest THC levels and providing a more trippy and psychoactive effect with more mental stimulation, rather than the lazy/sleepy physical body stone of over mature flowers. This all occurs because as the plant passes peak maturity, as indicated by all pistils being brown, the plant is close to death and with this comes an associated slowed metabolism. The slowed metabolism of the plant means that the THC is breaking down faster than it can be replaced, leading to flowers with heightened CBD and CBN levels and reduced THC content. (When THC breaks down, it is primarily converted to CBD and CBN, as well as other non-psychoactive cannabinoids) So it is up to you and which type of effect you prefer - a stimulating and mind bending high or a sleepy and lazy body stone with reduced psycho-activity. Personally I prefer to soar on a rocket ship and not smoke something whereby standing up seems to be too much effort and then falling asleep! You could also do a staged harvest and pick a bud with 10% white pistils, one with 5% white pistils, one with all just only recently all brown pistils and leave another until the pistils are well and truly brown. Dry them and keep them until you have all 4 examples for testing. Now for your homework - select a quiet day at home and smoke a bit of the 10% bud, wait a while for full effects to develop, then after an hour or so, go to the 5% bud etc and repeat the test with all the samples. This way you will find YOUR preferred level of maturity with an easy to identify "pistil colour" method of harvest determination, rather than trying to follow generic advice judging by trichome colour percentage alone, (which is highly subjective), which as I said earlier, has many variables and is not a true indication of the plants ACTUAL state of maturity or health. Had I harvested the 4 week flowering plant with 50% amber trichomes (actually more like honey) , which was a Blue Dream plant for those playing along at home, I would have been rather disappointed with not only the effect, but the yield too. Waiting for amber trichomes on a strain that never develops amber trichomes would mean harvesting near dead flowers, due to waiting too long and then realizing that I better harvest now or she will be completely dead. I have in the past left flowers until this stage as an experiment and found that I was mightily disappointed, the effect being weakened and not very psychoactive at all, but lightly body numbing and a huge let down. I thought I would have "super dope" by letting it get as mature as possible with (hopefully) bulk THC, but the outcome was completely the opposite, just meh bland sleepy pot with no real buzz to it. Needless to say, I only did this once! Anyway, leaving the plant until all pistils are brown means the plant is close to death. A plant close to death can not maintain prime cannabinoid health and cannabinoid quality. Pistil colour will tell you how close a plant is to death. Trichome colour will not. Amazingly, the amount of questions in this forum from people with near dead plants asking if they should wait longer because their plant doesn't have the prerequisite 30% amber trichomes is astounding and is the classic pitfall of judging flower maturity by trichome colour alone!! Now, that I have set you some homework - do a staged harvest and find YOUR level of preferred maturity! And make sure to compare them side by side, testing on different days or weeks will give different effects due to external factors and you will no doubt forget the small nuances that distinguishes the effects of the cannabinoids when harvested at different stages of maturity. Homework was never this much fun when I went to school!! Hope this helps and congratulations too, if you read my entire essay to your seemingly simple question.,............ Organoman.

Hi there,here’s my rule of thumb for harvesting period.During that time,the leaves will show deficiencies, yellowing and most of the white pistils become orange.The best method is using 60x microscope and check trichomes colour.If trichomes are mostly milky/cloudy about 80/90 % and fill with some amber colour, it’s the time to harvest.Flushing or not flushing is your choice.Happy growing... ✌️

Trichomes and how fat the buds are. Use your phone with your steady hand lol and see if you can see. If you're taking pics everyday you'll notice how the buds stop fattening 👌👍🤘

I will answer the question like this. Let's say you are blind and can't see. Gorilla glue has a 8-9 week flower time. So if you harvest her any time in that time frame. You will be happy with the harvest.
