Jwjohanswered grow question 5 years ago Dark green probably just means nitrogen overload along with your burnt leaf tips. Weird shaped leaves, I've seen people on here with that same question and they seem to say either a) the first couple nodes of a seedling, the leaves can look funky sometimes and b) some strains or even phenotypes just have genetics that grow weirdly shaped leaves. If leaves turning dark green and others having burnt leaf types, both likely indicating nitrogen toxicity, are all you see going on in addition to weirdly shaped leaves (there's no chunks missing out of them, no other signs of other nutrient problems, etc), I wouldn't worry about it too much.
In fact, plant A in my first diary had moderately taco'd leaves for the first few weeks of its life. I thought it was too close to the light, or too much nutrients, not enough water, etc... But nothing helped and eventually it just went away on its own around the time the plant changed from seedling to full veg mode.
