Ok where to start lol. So ur gonna have a big ass bush in that tent. When you do a scrog you will do whats called lollipopping. When you lolipop you will end up with probably at least 10 cuttings off that plant before you flower it. Do your initial lolipop 2 weeks before flowering then your next set of cleanup will be between week 2 and 3 of flower at which time u will basically remove everything up to about 6 inches below your scrog. This prevents you getting that nasty popcorn bud that really doesnt amount to shit for the amount of work it is to trim. The idea of the scrog is to create an even canopy of buds so that everything gets light. All those tiny little branches that form popcorn will now be tops. Take 1 of those cuttings and veg it out amd use the others in your tent. If you continue a scrog u will always end up wth enough cuts to do your next scrog. You can even preveg them so that you dont have to wait too long before flowering again.
When i said get nutes i just meant something to supplement the nutrients once ur soil runs out of them. Organics is great if u know how to do it, i dont so i stick to chemical lol.
Watch my new journal if u need an idea on how to do everything. Its probably 2-3 weeks away from flower so u should see it done before you do yours.
