DAMNNNNN Looking great .
A little over a lb per light. I found the 315s have more penetration, but slightly less density than standard HID. Instead of tops being incredibly dense and the bottoms not so much, the 315s produce a standard density from top to bottom.
I was running 600s before and would yield between 1.25 and 1.5 lbs per light. So they do not outright replace a 600, but watt for watt they destroy them.
Don't know a lot first hand about autos but I wouldn't fret about it, with photos there can be huge variations between strains and even phenos of the same strain in how they stretch and stack buds. As long as you keep them healthy they'll do their own thing. Not sure what you're vegging with but I've seen some extreme stretching go on with some phenos when changing from blurple veg lights to the 3100k CMH bulbs in flower. I've run a couple of fireballs that stretch like mofo's and end up with huge spacing between the nodes but eventually filled in pretty good.
. Well it's just actually grown about 4inch on top cola only in 10 days since I put under LEC. Veg was outdoor. Was two weeks in flower when put indoors. Hope to not have big fat cola in middle and nothing on top. Lol
That change from outdoor to indoor could have had some effects on it's growth, likely a certain period of adjustment needed. I noticed my outdoor slowed down when I finished the last few weeks in the garage when the weather turned crap a couple of years back. It eventually finished but took longer than it should have.
Keep us updated. im pretty sure that will fill out. It almost looks like it went in to flower stretched, started growing buds, then stretched again.
