I wouldn't call it bad gentics
Mutations in plants are just more noticed than slight Mutations with ourselves..weather it be a bigger base of a nail r big toe etc. And then, we see them really easy sometimes with ppl with disabilities
Its nature for things to wanna go their own way. All phenos are in themselves mutations as no 1 pheno is ever the same. So, never uniformed. Or have the same look.
I've had some of my best weed come off girls that started like this.
Keep it going. Pushing on and you'll learn from it if anything. Been said with any grow you do. Nothing major to worry about.
Good luck
