CXA grow 2

ok so my plans this time are gonna be different. though the results from my first DWC were good. about 1/4lb dry off one auto in a 5 gal. I didnt see much difference from that vs soil. so i think I may be doing soil/coco coir for my next grow.
IM going to go with Mephisto genetics Tyrone special (autoflower). I want to see if it can live up to the 65 day seed to harvest claim.. I doutb it. probably be 75-90 like most autos.

ive heard so much hype about this company on the auto flower forums that i thought id give them a try

my last grow with crop king seeds early miss was okay.. it did auto flower but it took forever to finish and the buds were okay at best.. maybe had too much pot for the amount of light.

ill be doing this grow with 3 plants in 3 gal pots and nutes will be left over GH nutes and later just flora nova bloom and veg. unless someone has a better 2 part .. I just want one bottle for veg and one for flower.. ive used flora nova before with good results. but if theirs something better id like to know

lights are
2 CXA 3070's 210W's total (3000K)
4 26W~ LED par 38 bulbs (6000/2400K)
1 24W 420NM t5
1 24W 10,000K t5

so about 360W's of light total in a 4x2 space. Im not sure if that is enough. if not how much more light would work for 3 plants?

Updates. I got 3 seeds germing right now. ill be using a 70/30 soil coco mix and using up the rest of my gh nutes to start. then moving to either the flora nova set up.. or possibly green house seeds feeding powder.. which is apparently one step. if i can find it for cheap enough. the soil.. due to my rather northern location (northern canada) Ill probably have to use some form of walmart lowes hope depto ect soil.. that being the case what would be the best crap to use?
