Pure Michigan Auto Grow #1

So these 2 girls have been growing for about a week & a half apart. So Pure Michigan is making its way for sure. Not liking the curling of the leaves though, thought it was a humidity issue, but after raising it to almost 80, doesn’t seem to be the issue. I only water once every 3-4 days and only to wet the tops of the soil so I don’t think it’s lack of water…? Top Gun is moving a little slower for my liking but, she’s going the best she can, overall with FFOF, I’m not seeing to many seedling deficiency’s or having any issues growing in FFOF. Please let me know if you see anything that should be of concern! Brand new grower on my 1st run so all tips and tricks would be greatly appreciated!
