Hey friend good luck on this one! Would it be alright to offer some advice to help you out? Cannabis plants love heat and humidity. It is the buds that hate it. So in veg we want to exploit that to get vigorous growth and veg fast to get into flower with good sized plants as quickly as possible. Temperatures of 80-84 are good for lights on & with lights off we want no more than 9 degrees less with lights off. We do not want to expose our plants to temperature swings beyond that as it will cause them to stretch in veg and in early flower. So we like to keep those temp gaps nice and tight, Also humidity of up to 70% for the first 2-3 weeks is great to help supplement the smaller root structure with some foliar intake from the humidity in the tent.
Secondly, if you haven't got them yet get yourself a good PAR meter & thermal laser temp gun like the fluke 62 MAX. These items will help you read your plant's needs and grow to them more effectively. Also, I would recommend you study VPD, Vapor pressure deficit and how it relates to growing cannabis all new growers should learn this right from the start. If you feel you should need any help or have any questions feel free to ask me I will help out as much as I can when I have the time to respond, I am on multiple times a day.
