That plant looks good. Personally, I'd let it go another week or so, but you can isolate one of those lower branches with a piece of cardboard (or something similar) to spray the lone branch you want to reverse. You don't have to maintain constant isolation, just do it when you spray. Once you see some actual reversal on that branch you'll want to keep a really close eye on it to catch it before it pops...but that's gonna be a good minute so no rush.
On the MG...I'm no critic. If it grows good cannabis it's fine by me. I ran hempy buckets and the lucas formula for a couple rounds a few years ago and it grew good weed.
This afternoon I decided to check on the stuff I took off the stem this morning. It has hung for 5 days already, but I want it crispy to palm-grind the seeds out of it...a few more days.
As I was fiddling with it, my wife grabbed a tiny bud smaller than a dime and rubbed it in her fingers. This is what came out...
These buds are perfect right now to jar...but they're not going into the jar
The small amount of flowers I got off this plant looks like what would normally be about 1-1.5 oz, but I weighed it and it weighed 136g...lmfao.
