If they're actually spraying fentanyl on a plant people should be dying. If you even touch that shit you'll go to sleep and not wake up. So potent it's not funny.
Hopefully it wasn't sprayed with avid or forbid while in flower. That stuff is so bad for you. If you've been growing a while you'll see the crazy lengths people will go to to save a crop from pests.
I have a verified glue cut. It looks like it yields horrible but wait until you hit week 6-10. It puts on a lot of weight.

Your canopy should be even across. You have one main stem and everything else is lower. Those lower buds are not getting the same amount of light. Ideally indoor you want a even canopy so all parts of the canopy get even light and produce more buds
Of course if you're comparing 5 gal hydro vs 5 gal dirt. However he has 2.5 gal hydro vs 5 gal dirt which he was using before. This is why I was saying he is in for a surprise when I think he will yield less in his hydro setup vs his dirt.
