Straight Fox farm "ocean forest" runs a lil hot for auto seedlings... I would do like a 50/50 of Ocean forest and light warrior... The thing with gettting big autos is root space... they have very limited veg time...and the moment that tap roots reaches bottom of its container ur maxed out on size.... so unless you do like the tier method I would start them in final pot... I personally use soil in air pots and have great results! Your yield will depend upon ur skill with nutes etc... LST I highly recommend you do this..this will greatly improve the yield.. no topping or super cropping.. causes stress.. and thats the last thing you want from a plant that you in know way control the veg time.. you want it spending all its energy into growth not repair... Hope That helps!
