Thin wide stem, undesirable genetic mutation?

Day 7 of flower, this specific plant is number 1 of 2 feminized golden lemons. 1000k hps, and a 2000w Bestva led I bought before I knew any better. Sensi bloom a & b are ze nutes, with the supplement line. Seems like shes flowering quick compared to the long flowering one I had outside of the same strain. This branch with the mutation on it is farther along than the rest of the plant as well. Anyway, is this a bad sign or just one of those things I wont find out till shes done?

The bestva is only a 150W equivalent and I dont check my ppm when I give nutes. I feed at 1/2 strength 3 times a week, less for some of the others. And I always balance my water

I had that last grow it was symmetrical so I had 2, looks weird but that's about it. Don't expect the bud to be double size though.

Have fun

Google polyploidy

This is a very undesirable trait
And easily found in GPS gear , I would cut the branch n toss it . Flower out the plant n not take clones .

I’ve seen at lease one of theses plants in every pack of GPS gear . And seen it in a GPS cross .
