DrJynx86answered grow question 4 years ago The weeks provided by breeders are the optimum, given the best possible conditions ever in a grow room. Light, nutrients, temperature, co2 intake and excellent care.
Not to say a home grower cannot get to the same level of expertise, but you also have breeders that will false advertise less weeks than real.
And you have one of the most accepted ways to test for maturity, peak trichome amber/cloud ratio. Meaning growers usually target a 30-70% amber/cloudy ratio, with none or very little clear trichomes.
In any of the three scenarios you're still very off. Please give your plants the extra two or three weeks they really deserve to fully develop, you will definitely notice in the quality of the final product.
As always, you can try just harvesting some buds that seem done by now, and the rest weeks later, and they will develop a little bit faster.
Happy smokes!
