I have never seen such a huge difference between phenotypes. On the one hand, I have the best plant ever. Not even a close 2nd. Its fast, heavy, so full of resin that I can't even believe my eyes, purple, and just amazing in every regard.
On the other, I have one of the worst. It's taking forever, it has no resin, the buds are pretty much non existent (just hairs, but no buds), and I am this close to just cutting it down so it stops blocking the light.
So anyone who is growing SLH for the 1st time needs to consider this. Don't give up if you get a bad pheno, there is at least one amazing one out there. And you can't go by the way they look in veg. Both of these looked great early on, but this 2nd one has nothing positive to offer beyond that.
