Hey Growmie,
As someone who has been growing autos for 7 years, you're off to a solid start, especially for your second run and first time with autos. Your setup looks dialed in with the Mars Hydro tent and lights, and you're doing a great job logging everything. Just a heads-up since you're using 0 PPM distilled water in coco, you’ll want to supplement a bit more Cal-Mag, even though Sensi Coco includes some. Your temps and humidity are on point for veg, but start bringing that humidity down as you get deeper into flower. LST timing looks good, just keep it gentle with autos. Keep an eye on your feeding strength, start light and increase as needed, especially with a full Advanced Nutrients line. Even though it's pH Perfect, still check your runoff here and there to make sure you’re in range. You're documenting things well, and the community engagement is great. keep it up and trust your instincts, you’re on the right path.
