AsNoriuanswered grow question a year ago Its seed start, not clone. So as ou would look into big family all brothers and sisters are not twins.
Same here,one is stronger and takes a bit low ph, maybe too intense light, 24 hours no sleep ( i would go with 18/6, plant needs rest ) way better than other.
Same with feeding ...
But generally you should tune up setup, something works wrong, they should look way hapier even with genetical differences.
Good luck in sorting up !!!
