I'm still new as too my friend, but sometimes it's easy to get confused between those things that look like hairs (can't remember the name) and actual hairs !
Its all new growth. Most of my autoflowers usually showed sex around 30 days give or take a few, so you should know soon enough. Sent from my LG-K371 using Tapatalk
Not necessarily. Autoflower in is an inherited gene, similar to how some plants have different colors due to genetics. Whereas feminized seeds are made through a few different processes (colloidal silver or hermie seeds). Sent from my SAMSUNG-SM-N910A using Tapatalk
Idk if you addressed this yet but you have a little bit of tacoing happening there. I think you might need to to fine tune temps humidity or light distance to help with that. It's most noticeable from the angle in your 2nd picture. Sent from my SAMSUNG-SM-N910A using Tapatalk
Yeah temps where I'm at have been high this month. I ran some ducting from my central a.c. into the tent and it is helping a lot.
