Hi I was looking at your grow from the beginning and I only have 1 possible recommendation, autos need good hours of light to bulk up..especially during the veg cycle. I wouldn't say 24 hours of light, but definitely 18-20. Since its an auto it doesn't necessarily need that reduction of light down towards the 12-16 range. Maybe give that a try next time? Once their not tiny seedlings, boost those babies up.
Happy growing and congratulations on making to flowering and harvest time.
