I like the look of that LR#2 bud, she looks frosty.
what are you using for flower nutes jm?
I think that crispyness is because they are hungry for flower nutes. P or K, could go ether one really.
I was thinking that if you are using a good flower nute, and using it full strength. Maybe there is too much calcium causing a potassium lockout. Understandably you want yellow fans near the end, but they are a bit too cripsy. And i can see your yeild has taken a hit.
Don't get me wrong, they are bigger than my autos, atm. But you should be hitting well close to the oz/per plant mark being that big. Your extra lights will help, but you should get a larger bud swell than what they gave you.
Don't want to sound like i'm nit picking your grow mate. Just thinking about it as if it were my own.
You should be able to squeeze more out of that space with a few tweaks
