It looks like he is in smart pots, if so it woild be hard to be root bound. It kind of looks like the "hot feet" . Some plants will get that when their roots get down into the super soil level.
Make sure your soil does not dry out to quick in those smart pots though. As the soil drys out you...
7 gallon of soil is enough to grow plants with 8-12 zips on it easy. 2 month veg and 2 month flower. Under 1000w. With temps, humidty and stress levels in check.
Well to answer the OPs question and affirm the other reasonable people's opinions here, yes you can use MG.
Someone was a sandwhich short of a picnic when they replied to this thread several times... still no word from the sandwhich.
Cool man. I have actually placed in local brew comps but I rarely brew to the style guidlines for bjcp judging.
I am usually brewing them too hoppy or too high gravity, or turned it into a "specialty" beer before I am done.
Most everything is a boil additive, all I was saying is that I would try the bud in the mash based on my experience.
Now its like well have you won any awards? Hahaha
Also, I am not saying this is the only method. But it is a method. If you want to go thermo nuclear on them things without the nasty radiation bit. Then there you go.
And even cockroaches wont survive.
To avoid the whole "plant contamination" with nps. After each cycle, clean your garden...
I've done some research on the subject. And these post sums it up well so we dont need to re hash everything.

TLDR...
Yes the starch conversion is primary reason for the mash.
I have been getting dual purpose from my mash for some time now. I will "steep" adjuncts like pumpkins, ghrahm cracker(yeap), to name a few.. in the mash to get their flavors into the beer.
Also, I have never done an infusion. But, my guess is if you wanted the ganja flavor then I would mash with the flowers to get the essentials from them for flavor.
If you wanted the weed buzz. I would go the green dragon extract and add at bottleing.
Hmmm I will research this more.
Put a hot shot no pest strip in there and leave it for a dew says. Overnight make sure the fans are off and it will take care of bugs, larva and eggs. Thripes, mites, what ever will be done.
