They look good, a bit bigger than what I would have done, but they will be great. Having that extra bit of soil is fine, and will allow your rootball to do anything it wants, they usually form outward, and not so much down in that kind of medium with those kind of bags, so round is always good, especially if you've got photoperiod there, which is what I took them as being. (I don't see auto's written anywhere)
As for the cool temps, that can be a good thing. My plants often get temps in the high 50's and low 60's all though the nights, it's just warmed up here lately, but I think last night was 61f, so still relatively cool. It's the only way your going to get them deep purple colors, and nice unique terpene production. I dry out the air some by using a dehumidifier/air conditioner unit. One of the portable jobs, it does an excellent job of controlling environment especially with LED lights, although it looks like you've got quantum units, which run much cooler than my big LED units, with onboard drivers. edit: I do see your dirver, if you can get that off the lights, and above/out of the tent, that might be useful also. (again, your in canada? so you know best) You certainly don't want it getting over 75 degreee, if possible, below that is optimal.
They look great.
I would maybe dial them down a little, (small amount) as long as there not getting hot. Usually I can get them within 18-20 inches, but you've got to watch them, see if they can take it. But don't attempt that until you make sure there responding well. Every LED is different, some I can dial down to inches above the plant, some have to stay off. What are the size of your diodes? How many watts? (I've currently got some 6 footers within 6 inches of the light, and it's ok) I think I"m going to put these outside to finish.
I think the 1 and 2 gallon pots are idea for inside, as they seem to be optimum for root ball development of 4-6 foot plants. Also, I get that some of the advanced grower want to see you do something in a beer cup, but that's advanced technique, and if this is your first grow, I think you certainly made a wise decision. Much less to go wrong here, and your plant can reach their full potential...
