m0useanswered grow question 3 years ago Yes plants will mature at different times if they are different strains and if they are widely different phenotypes.
Plants will also mature on the top most growth first and then work its way down the plant. That's why a lot of growers like to use the SCROG method to keep an even canopy vs a Christmas tree like effect of how cannabis naturally grows. that's why LST is very useful in autos.
But your harvest time will be dependant on trichome maturity.
10-30% amber is best. I am for 10%.
As for time left till that happens, I would like to guess 2 weeks.
Its hard to guess as you just need to check every other day.
Best of Luck and Happy Growing!
