Not all plants will "canoe" or "taco" when they are over fed. Some just get extremely dark blue hues. Some tips burn. Some curl under or over. Some will crinkle and turn golden brown. It depends what kind of nutrient burn or excess they are experiencing.
Canoeing leaves can also be caused by mag def, heat stress, plant moisture stress etc.. Canoe leaves isnt a tell tale sign or indicator of 1 specific problem. It can mimic a multitued of issues. You might just supply them with nitrogen to the point where all they do is turn very dark and blueish hues with burnt little tips. But if you keep going something worse will eventually happen. You just may not have reached that point you know. It depends what the plant is uptaking and using etc..
But I hear yah. If you think youre good to go no worries. No harm no foul not trying cause a fight at all. Its all good man. Take care
