Love the grow! You seem to have it under control.
I am new so take this with a grain of salt.
Scrog can really be done in many ways. Personally I defoliate more than most, about 75% of the leaves at a time to encourage the lower sites to reach the net. This can be done to end up with hundreds of tips instead of a few, dominant colas.The tips however will be exponentially smaller buds by then end as the plant has a genetic code to produce a certain amount of bud. For my first grow, I took this really far and am sitting on hundreds of bud sites in a 3x3. Take a look at my diaries, may shes some light. 👍
