nice pix tru, they look real nice
you could chop around 60 days but they generally arent at their peak until 70-80 days,sometimes even 85-90ish days.....
so check the trichs on the plants regularly, as some of the plants will mature faster than others...
i wait til the Pistils stop growing, and then check the trichs..
You can take a test nug if you wish, just dont get greedy
dry it in the microwave on low power, i use the defrost setting if i ever do that.
As for your reg diesel, when to flower depends on several things..ie are you gonna take clones from it to keep the genes, how much head room you have in the cab etc
Starting 12/12 in the last few days of the Autos life is prolly when i'd do it...
Time to hit the hay
