Hey mate, the grow/plants look very healthy, definitely a nice job!
Only thing I keep on asking myself is why there are so many growers, including you, that use support-nets as their SCROG-net? I ofc don't want to be rude, but what you are doing is more bending/(super)cropping in combination with a support net so the plants stay upright and with an even canopy. I bet if you take away the net they would probably stay in the same position. With some varieties, with strong stems, you wouldn't probably need the net and grow them freely exactly the same way. But don't get me wrong mate, you do an excellent job at maintaining a healthy and vibrant canopy, and they look really on point and dialed in!
Personally my idea of a SCROG and I have been doing that from the start of my 'career' is to have a strong net (from metal) with smaller holes, usually 5x5cm, so there are many spots/crossroads on the net, to fix them to with tie-rips. This way you can even spread them better and get more buds. The net you are using (support-net) can be used on top to keep the cola's from bending over late flowering. But hey, maybe it is just me that thinks that way, or I am already considered and old-school grower haha.
You should really give it a shot with a real SCROG net, some use chicken wires netting, but tbh the holes are usually too big, and when you take the chicken wire fence net, too small. So the best tip is to use this :

In Dutch they called it a Aarde mat - it is used in bathrooms, flooring etc. It will transform your SCROG experience! When I think of it, I'll share a few pics of SCROG's done with this type of netting.
Nice big plant mate, well done, shame about the budrot, you see that backbud in the picture, completely brown already ;-) First time seeing our Auto Trichome & Cream foxtailing like this, looking at the rest of the bud structure, it kinda looks like a second bloom phase. Could be the environmental conditions, what do you think?
Again, solid growing mate! Regarding that test you spoke about, with doing one room with heavy defol and the other without, are you planning to do that with clones or not?
Using (autoflower)plants from seed will definitely not give you the right data to work with. I love the idea, and would love to see it being done, but hopefully you can do it with clones and have 2 rooms that are exactly the same, same equipment, same climate etc.
Anyways, keep it up, and if you are ever looking for some genetics to try out, just holla at me!
