Hey StickyThumbz94,
With 78 fahrenheit you have a nice temperature :) Plants love to get 78-81 and some kinds can even go higher or when using co2.
Getting lower temperature at night is a good thing to have but don't get lower then 61 because your plant will stop flowering.
So 70/72 at night is awesome.
I even know growers and did it myself to that lower the temperature in the last few weeks daytime and nighttime to get more collors in the buds if you have a strain that have thoose.
Only do this if you are knowing what you are doing.
Just try to keep your medium(soil) wet, but not to wet since i see many light can reach your pots since you don't have big fanleafs anymore. Because of this your pots dry up faster.
To be honnest i still think your plants can flower for some weeks.
If they like to drink everything you gave them in like 1-3 days they still want to flower.
When the hairs on the buds are 80% brown and you have milky THC(thricromes) instead of crystal ones, your thc is ready.
Looking at your diary, i still see many white hairs indicate that she is not ready yet :)
Good luck growing :)
