HOW ARE MY PLANTS DOING? Day 13 of Flowering

So I'm a first time grower with many questions and concerns. All the help would be greatly appreciated. My temps range from 70-79 during the "Lights on Cycle" and 77 to 63ish during the 'Lights off Cycle". I have a very standard build of 4 Sour OG Hybrids from clone cuttings. As you can see living in Southern-California my temperatures are very high during the day, so i resort to night time light schedule. The problem is I have troubles dropping the temperature during the night hours. How bad is this for the plants health?

Any information would be greatly appreciated, attached is a picture of the girls right now.

looking really good here! don't worry about the temps so much, your stressing your girls out
