Totally new to this! Cheese bomb and AK49 autoflower

Hi, i am doing my first ever grow i am growing cheese bomb and AK49 my cheese bomb has just started flowering and has rapidly grown, how big will this get lol? My AK49 is an autoflower and is flowering a lot quicker and is only about 2 foot high both have only been flowering for just over a week, the ak is clearly flowering well and the bomb has little flowers, anyone got any knowledge of these strains and any advice and tips would be appreciated, this is my first grow and im just happy they are flowering lol and want to make sure i do everything right from now on. The cheese bomb isnt autoflower. Cheers

If they`re healthy and flowering, you`ve done everything right. If it aint broke, don`t fix it. Keep an eye on the top heavy branches and don`t bang the bottom of the bottle, the ketchup will come out on it`s own,....If ya know what I mean !i
