Oh man information on the net gets worse.
Three blades isn’t a sign it has ruderalis in it that’s nonsense.
I know what there getting at but it’s been put very badly
There a whole load of factors why your plants leaves have 3,5 or 7 blades including the fact that some plants develop more blades as they get older and stress can cause some to revert back to three.
pure ruderalis is ditch weed that has no thc and will give you a headache
It’s been breed into autos as ruderalis flowers once it reaches a certain age no matter the light schedule
It’s been breed into some strains to make plants automatically flower without out light changes.
If you brought a packet of seeds that said they were photoperiod from sensi seeds I very much dout they sent the wrong seeds as they haven’t ever done that to me during the last 30+/- years I brought from them there pretty good in that area.
Basically your plant is what it said it was on the packet.
Forget the amount of leaves it has it looks good and healthy
