Some strains benefit from 24/0 or even 20/4 .....
I run Autoflowers more often than photos ONLY BECAUSE OF PERSONAL CHOICE.
Autos are tempermental sometimes and you have to pay close attention to how you grow them . They do not HAVE TIME to recover from screw ups like a regular strains.
They are sensitive to overfeeding , overwatering and general too much fiddling with.
I run 18/6 light yes STRAIGHT THRU HARVEST , they do not need 12/12.
They will transition to preflower within 30/40 days. They DO NOT need to be Supercrop or any harsh handling ..... Just plant them and let them rip ... I LST them only and rarely do topping ( strain dependant) .... For personal use these are hard to beat.
Feeding :
Basic nute lines work well ( 2 part grow and bloom ) : like GH MAXIGROW / MAXIBLOOM
or DYNAGRO or something similar .... They have a short veg cycle so using multi bottle crap like AN NUTES is a waste. Veg stage is around 5 weeks. If you use a mild soil mix - happy frog or similar will GROW her all WITHOUT added Nutes. I use Lowe's Vegtable garden and have kicked FOX FARM to the curb. I water with tap , no RO , DISTILLED or other water bullshit. If you PH your water or feed mixes to 6.5 , then you are golden.

I plant seed straight to final pot size ( 3-5 gallon ) - some will argue this point but it works fine. No growing in party cups .... This plant will start to take off around the 2-3 week so why would want to disturb it to pot up ???
Mist seedlings , no need to drown pot with water ..... Yet. I mean there are tons of suggestions but once you see they are plug and play , you can keep a harvest rotation every two weeks like I do ...... Hella easy.
