Such a beautiful sight! Amazing sativas Tokaite:gthumb:
They look like old hazes and thais/vietnamese, I bet many sativa lovers would drool seeing your trees
152 days sounds extremely long in the auto world, but equatorial sativas usually flower that long and more, between 15 and 22 weeks from switching, have multiple flowering stages and kick the mind up in the sky
I have a suggestion in case this whole grow session will end simultaneously, switch to 10hrs light/14hrs dark(or even 9/15) for the remaining time.
