3 Leaf Seedling

I’m currently starting GG4 and the seedling sprouting today but it sprouted with 3 starter leaves. Is this common?
And also I’m currently finishing up White Widow Auto (below).. she @ day 54 (I think week 2 or 3 of flower - can’t really remember.. autos grow so quickly!) but how much bud do you think is possible?

Your WW needs another 3 weeks. Looks pretty good!

Yes the three leaf seedling is common enough...it could perhaps be a polyploid or just a glitch in growth and the seedling will grow out of it over time. Time will tell. No worries either way.
