I was a bit behind on my timing too, was counting it from sprout, when its meant to be from seed. So I actually started seeing trichs at day 36.
Your grow's looking good mate. Ive been chatting with someone in the auto flower thread who's got a load of these on the go. He says there are three different phenotypes: the xmas tree, one main cola, minimal branching - the bushy, multiple branches, not very tall - the monster, much taller, obviously sativa, multiple branches. From the look of your pictures you've got mainly xmas trees, with at least a couple of monsters. This is good
the monsters are the ones which produce the big yields which people occasionally report (4oz from one plant is the largest ive heard). This guy says that his favourite is the xmas tree, because the one main cola fattens right up and gets huge. So it looks like you've got the perfect phenos for your grow area. Looking forward to following your journal to the end - and blazing a couple to celebrate what im sure will be a very successful harvest
