Brand new here and looking for help

This is my only Early Wonder Skunk - Solar Warrior.

OK I got a loom off Ebay and it hooks up to my iphone so this is what I have. I will try and get better ones but i have a brace on my left hand and it is really hard to stay steady and I am still trying to figure out if I have it set on the best setting.

Ok so give me some answers. Am I doing the best job that I can taking the top off in the morning and putting it back on at night? It was 34 here today and will stay hot all week. I do see condensation on the inside of the top of the gazebo. I don't think I will need to put a heater out there just yet cause it is still in the 2 digits at night. I stopped the 20-20-20 what should I get and how often should I get it. I don't have access to any pot places just hardware stores for regular stuff. I can't put them inside cause I don't have any lights at all. I have mil jugs of water and they just got 5L each and they are in 21 inch black pots. The sun is gone so I have put the roof on and the sides. Thank you guys for all your help and tips. I think the Worrier is just about ready. i see the tricomes and they are mostly clear still.

Ok as well how can you tell what the THC is in your plant? And is there any way at this point to make them finish faster?
