Are they almost ready for harvest?

Looks like your plants are not there yet for my preference is more than 80% dark pistols compared to white and10 % amber trichomes. Also I look at the lower buds maturity to make the final determination. I use the trichomes as the main determination for a harvest so if you have around a 20x magnifier and can see approx. 10% amber trichomes and the rest are cloudy it's harvest time for myself. I then like to leave them in the dark for about 2 days and then harvest. Looking well good luck @GreenSwordsman

I agree with Green Hornet, they aren't ready. I would guesstimate at least 2 weeks yet.

Agree.. give em another 2 weeks watch those buds swell some more and firm up.
