Plant 2 has less trichomes than plant 1, despite being the same strain. The hairs are darkening and curling earlier, and the calyx have slightly purpled tips. Is this just unlucky pheno? Or if it's signs of something wrong, then what could it be?
Just a different in pheno.
Unless you had multiple issues growing such as easily over or under Watered. Or easily over or under fed.
Even with those issues I would say it was caused by a more issue prone pheno type of said strain.
