@FLOGROWNDIARIES, Autoflowers are the only thing I grow and, unless you're an experienced gardener, they do NOT like to be transplanted... the rule of thumb with autoflowers is that you germinate them in the pot they're going to finish in.... so all my germination takes place in either 3 gallon or 5 gallon fabric pots!
As for nutes, they don't like or need them for the first couple of weeks... depending on how they grow, you might start nutes by week 2 but whenever you start them, only start with 1/4 strength... the next week you can up it to 1/2 strength... and again depending on the nute brand you choose, they may never be able to go to the full strength... I use Fox Farm and never use more than 1/2 strength grow nutes... and when they get into flowering, I cut those out completely. You'll have to monitor your plants carefully to figure out whether they're tolerating the strength level you're giving them... And BE CAREFUL with any soil that already has nutes in it.. too often, these soils are "too hot" for autoflowers.
Water when the plant tells you it needs water... this will be difficult to assess when it's in the early stages of growth but as it gets bigger, just lifting the pot to see if it's heavy (nothing needed) or light (needs something).... and always follow a water/feed/water/feed routine.
Good luck to you - and enjoy the journey!
