After looking at your diary, the plants pictured still need 2-3 weeks to fully ripen..............Saturday would be way too early.
Trichomes are not everything when it comes to harvest, despite what people might make you believe..........there are MANY genetic variables...............basing your decisions on a single factor is not ideal, you need to look at the whole plant.
Some plants never get amber trichomes, leading people to harvest over ripe, near dead plants after waiting too long.............some plants that I have grown had 70% amber trichomes after only 4 weeks of flowering............. that then took another 6 weeks to be actually mature.............so basing your decision on a single factor can have flaws........pistil condition is a real factor in determining maturity.
