You can use both spectums of light for autos,T5 6500k for veg,4100k for bloom,HID mh for veg,hps for bloom. I've grown a lot of autos under straight T5 6500k veg bulbs for the whole cycle,i've also used the 240w blackstar led flowering light for the entire cycle with no ill effects. For optimum results use both. Autos are not fond of transplanting,they are prone to stunting. If you have to transplant use the tier transplanting method in party cups to lessen root disturbance. To do that use 2 party cups,1 you cut the bottom 1/3 off of the cup and slide it into the full cup and fill with your choice of grow medium. When you transplant to final pot,make hole in soil big enough to bury 1/2 a party cup deep and GENTLY pull the inner party cup out of the full outer one. What you will have is a 2/3 party cup with a root mass hanging out the bottom. Bury the rootmass and 1/2 the party cup into your final pot and that should keep your chance of transplant shock to a minimum. Most autos have a smaller nute appetite then their photo cousins,don't feed them full strength nutes like photos or you could burn them. I usually look at the photos feeding schedule on the nute bottle and cut it in half or 1/3 and see how the plant responds and work it up from there. Autos don't do well with defoliating,if you want too open bud sites up,tuck the leaves instead of cutting them off. Those are the main things I can think of,they are potent smaller cousins of photos that you can harvest from seed to weed in 70-80 days but the shorter growth/harvest times has its tradeoffs as far as the above mentioned items.
