Looks like it's very close. Trics still look mostly clear. As to temp it depends on the strain. Some strains can handle cooler temps better then others. Just make sure no frost gets to it.
I'd just carry on. Can't always have a perfect setup. Have to learn as you go. If anyone could answer this for me. What ever happened to just plain ol potting soil? Does having something other then dirt make that big of a difference?
I'm not a pro. But you have a lot of tips that are yellowing. Someone hopefully will point you in the right direction. Other then that it looks awesome.
