As soon as you notice the plant isn't getting any taller in the flowering room you will start to see the bigger, lower fan leaves turning yellow then brown. The fan leaves are responsible for turning light energy into an energy form the plant can use (photosynthesis). As the plant quits growing in size to concentrate on flowering, the larger fans are basically "used up". Rather than send energy to a plant part no longer necessary the plant shuts that part, the fans, down. Remember to remove the yellow fans after they are more than 50% yellow. Your temps are fine. If you water until you get runoff then make sure the pot is pretty much dry before you re-water. I put nutes in my water and water daily. But then again I run a "hot" perpetual grow. I harvest 2 plants a week and like to grow 'em "hot". By that I mean I grow with lots of nutes, a hot light and short bushy indicas. 85% of my finishing plants are self-generated clones. Most are in small pots of 3/4 to 1 1/2 gallons. After clones are rooted they get around 3 1/2 weeks to veg and 5 1/2 to 6 1/2 weeks to finish flowering. That's fast -- from clone dome to scissors in 9-10 weeks. Works 4 me, good luck, BigSteve.
