Stayblazin & Mersaides you both have some time before you can even think about harvesting. The plants are still growing and taking off by the looks of it they need at least 3-4 more weeks until it's mature and ripe enough to chop.
Stayblazin The cold temps will give your bud some color
But I would start to worry if temps drop to freezing wich I doubt in the next 3 weeks The plant will adjust remember guys marijuana is just a weed.
I have an outdoor going and I germed my beans in march and they still need 2-3 weeks before harvesting so please be patient and let em marinate so you can have a nice harvest..
Anyhoo Good luck with your grow if you 2 have anymore questions go ahead and ask that's why we are here for to help eachother out!
