sometimes plants can have nodes with three branches coming out of them instead of two, it's normal. some even think these 3 branch node plants are mutations that can possible yield more than a 2 brand node plant
think of it as a lucky four leaf clover... and im not sure how much more u expecting from only 6 days... they are a bit small... but look fine. post more pics as they grow.....
Theyre fine....u never changed ur soil I see....that plant may have three branches per node...ive had it and its just a bonus. ..or it may grow out of it its still very young...its not bad or anything tho...watch em as they grow n ull see the diff...the one on the right is "normal" and will be more symmetrical
My first grow I had a seedling that sprouted the same way.. everything worked out fine and I got a pretty decent harvest out of her in the end. Keep it up man looking forward to seeing how they turn out.
