Since they are feminized, they are actually S1 seeds. But otherwise I agree about the different phenotypes, something that fem seeds are quite notorious for.

For Bibbsy, just remember that plants from seed will all have slightly different needs in terms of nutrients. Giving them all the same mix and strength works sometimes, but sometimes not.

I wouldn't veg them too long with just a 400w. Remember that the plants will double or even triple in height after the switch, and light intensity decreases exponentially the farther away the light source is. Without some training (LST) to even out the canopy, you will have really nice top nugs but a lot of fluffy buds on the lower branches. You can easily cover a footprint of about 2.5 ft. x 2.5 ft., even up to 3' x 3' with that light and a good reflector.

Got any pics?
