This week, I had to cut three leaves—two smaller ones that looked like some kind of insect had laid eggs on them, and one of the big sun leaves.
Finally, I can see some brown trichomes on the B-grade buds. I thought about harvesting soon, but it will probably take another two weeks or so... Or I may have to harvest her week by week. I haven't decided yet.
What I can say is that increasing the amount of fertilizer has helped improve the health of the leaves. I should have increased it sooner; it seems that autos need more nutrients earlier than photoperiod plants.
