Hello there! Glad to see a fellow scrogger. I'm just starting my SCROG and looks like you're off to a great start. One thing I noted is that you said you were going to fill up your screen 75% before flipping to 12/12. In my experience, plants will STRETCH the first few weeks of 12/12 and will effectively double in size. If you are unfamiliar with the strain, I'd play it safe and fill 60% of your screen before you flip.

If you have a healthy amount of tops (which it looks like you do) you should be able to fill that screen up in no time. Another tip I've learned is to keep pushing the tops under and training the first 2 weeks of 12/12. Helps a LOT on yield and making sure you little cabinet doesn't turn into a jungle. I'm definitely going to be following this thread.

Keep up the good work!
