Nice cross either way. Dialing in specific strains can be an issue especially when running multiple strains at once. I used to run 10+ different strains at once and attempting to dial each one in to its peak is impossible.
Now I run a few phenos and then run a single per specific clone and it allows me to run just one nute regiment.
You said that one was from seed. It’s happened to me before. It’s either 1 a late tric producer or 2 it’s bad genetics. It’s not your lighting otherwise you’d have the same problem with the other plants. I had a football sized haze hybrid cola once and it didn’t produce shit. But I grew a bunch of them and it was the only one that did it. Cheers!
