Mutated growth

Some are saying keep it, some are saying toss it - I'm in the "toss it" camp... I think you're making the right call... Good luck!

High Candog, living things are not perfect and this is caused by genetics. Just continue growing like you are used to and this freaky special girl will turn into a beautiful cannabis plant like her sisters.

I have seen leaves like this on my first few plants I grew. Dinafem Purple Orange, when I looked at the time it said its normal for some strains. My plants grew well and yielded just fine. Unless you are short on space and time I would let it grow out and see how it goes. that's just me though. Good Luck!

doesn't bode well, and will definitely fall behind... but some of those do grow out of it... all depends on your context wether is is worth your time. if the space would otherwise be empty, keep it... if you can fill it better with training, toss it. my 2 cents. I like to plany 25-33% extra so i can just kill any laggards or retards. it's the only way to ensure consistency. if only 3-4 seeds you have a good chance of all 4 being fine.. but at some point of planting more and you basically guarantee a retard shows up.
