When would be a good tome to flip?

GSC Week 7 of flower, everything is going great. I cut the nighttime temperature down to 18c and they are starting to show some colors. I cut the ppm in half and stopped the bloom booster. I might give them one more small feed and then just water for the last couple feeds. They are very thirsty, drink almost 3 gallons every days.

Week 6 of flower, they are still growing lots of new pistils. I think this is probably a 9 or 10 week strain. I feed 1000ppms with not water between feeds and they love it, my runoff comes out at around 850ppm.

Starting week 7 for the blue raxx and week 8 for the GSC. Both strains are doing great and smell amazing. The GSC is really starting to change colors from the temp drop at night.
