I haven't tried it myself yet, but a bag of MEGACROP will get you through a full soil grow if wanting a "1-part"
They just came out with a new version that is finer and easier to mix. It isn't liquid , but is a dust, and you get much more because you aren't paying to ship liquids in bottles.
My plan of attack would be, get some quality potting soil that has dolomite lime in it and a larger pot.
Do a transplant, once the plant seems to be thriving from the transplant, start with 1/4 dose feed every 2-4 waterings.
Work your way up from that and learn what the plant wants.
Where you live will determine when that plant will flower. You might expect this plant to get 2-3 times the size if all goes well
If you don't want it to get too big, I don't know what to say lol. It is still vegging and I don't see much flowering.
A bigger pot is nice because it means less watering!
I don't know if they're doing the "free" samples that you pay only shipping for anymore. Those will last 1-2 grows
