You could start switching over to bloom nutrients, depends on the strain and how long it takes to finish but say midpoint of your grow you should be switched over, your plant looks healthy and is starting to bud out so i'd start switching over, probably would of done it a week ago, but that wont affect anything really, also you could start to use that bud candy (water) as well or say in a week and half to two, as you might as well use it up, but you probably won't need it.
I'm not a big fan of advance nutrients not that your asking for an opinion, and i'm not saying they cant grow good bud, but something to think about the next time you buy, is they are notoriously bad for selling diluted fertilizers with fancy names targeted and hyped for the canna community and are mainly just water in multiple bottles that you need to combine, compared to solid salt base nutrients, which when you think about it creates alot of waste from all those bottles that are used to hold all "mainly" water, and the energy needed to ship all that water around.
Like i said you didn't ask, but i just kinda cringe when i know how much money is wasted on theirs and similar products and how much waste and energy is used to transport them, something to consider and look into next time if you want, as its always better to have money in your pocket that you can use for other things.
. A bucket will work just fine.
