You may be able to find some simple grow nutrient kits that have like 4 or 5 bottles, but all in one is not really something you’ll come by. The different nutrients you buy are meant to support various aspects of the plants growth and provide a variety of nutrients the plant needs. These levels vary so much from plant to plant an all in one everything feed is probably way to impractical if not improbable.
If your on a budget and looking to get away with the bare minimum, there are people out there that just plant the seed in some dirt and just add water. I can’t speak to the yields or quality of bud but the main ingredients to grow are there.
If your looking for which one you should grab above all others, would advise remo nutrients MagNifiCal
It contains nitrogen, magnesium, and calcium, all three are probably considered to be some of the most common deficiencies you can come by.
That being said you can still come across other deficiencies and probably won’t have an answer with that set up alone.
Good luck and happy growing man
I’d suggest you ensure you have a ph tester for the water as if you are going to invest in any nutrients you could just be throwing away money if the ph isn’t right, cause your plants won’t uptake the nutrients as efficiently.
