First grow - Newbie Lemon Tree

think of it this way.. the other plants are feeding more "mouths" .. (aka extra axillary growth by comparison) ... so it's probably not growing "faster" despite most of the growth focused on 1 primary cola. if it has same total leaf area and same rootsystem, it's probably growing just as fast but concentrated in one spot... or if any of these things are lacking actually growing slower when you measure it all and tabulate it. all sorts of variety in gowth patterns is possible... genetic depression can reduce axillary growth as well as overall vigorousness of growth. i think it's mistaken as "sativa" pheno at least some portion of the time at this point. inbred "outcropping" plants quickly turn to shit after just a couple generations.

Yellow leaves near the bottom should be OK to remove. If yellow the plant has already scavenged the leaf for the nutrients it needs and the leaf probably isn't providing a useful contribution to the plant.

Unless you’re looking for a sedative high - which is gettin to the point where the thc is degrading into mainly CBN - I’d chop it within the week. I see it as peak thc potency within the next week. Gorgeous looking buds - better than most “vets” out there
