Lemon OG Haze Autoflower

So.. I know I'm starting this late in the process, and I've grown before, it's just been many years since. On a side note, YAY for MN finally signing recreational marijuana into law. That being said, I'm preemptively getting some plants going for the day the law takes effect. Any suggestions or help and ideas would be greatly appreciated since it's been at least 12 years since I last grew any of these babies, and When I did, they were photoperiod strains. So autoflower is kind of uncharted territory for me. I'd say as of posting this, I'm week 4 or 5 in veg state, and I'm noticing that the White Widow is not growing as much on the lower part of the stalk as the Lemon OG Haze is. both are on Growth Science brand nutrients and the current mix is: 1tsp Base A 1tsp Base B 1tsp Solid Start Per gallon of water. With each plant getting about half a gallon of water a week. So yeah, there's the start of my story. Any tips, thoughts, or help would be awesome! I'll continue to update weekly(hopefully) but as much as possible. Thanks for looking!
