First Time Growing Anything

Finally, 10 weeks from the time when these White Widow autoflowers first sprouted I can see pistils! So, I'm going to say that they're in flower now, although pre-flower might be a bit more accurate. 6 days ago I cut their light from 20/4 to 12/12 and about 3 days later I saw pistils finally forming. I suppose this could be a coincidence, but I'm coming down on the side that says even though autoflowers hypothetically don't need light reduction to flower, in reality sometimes they do! Otherwise, as the photos show these are large (for an auto), lush, and healthy looking plants. I'm looking forward to seeing what comes next!
