What is the best time to SCROG in the plants life ...

depends what you want out of your scrog. So if you want to scrog in order to increase yield, you really want to start the scrog during veg, as early as possible, threading the plant through the netting to create an even canopy from whence the plant can start making colas. You'll be putting the scrog up as close to the plant and the pot as possible, really really low. you're not really past that, but it's a bit late for that. Other idea is to use the scrog to support the flowering and kinda mush the canopy and leaves down to make an even canopy, you can do that right now, but it won't help increase the yield. So in summary : you're a bit late on the scrog, but you can still use the netting to support the flowering in a good way. no worries ! hope this helps ! 🚀
