Hello GutterHoe, Your girl is looking great.
I see you already started training her, your a good dad 👍
To answer your question, your plant need Nitrogen-Foshpor-Potassium (N-P-K) as her food also calium and magnesium.
And it would be helpfull to use something with sugar for the soil. (molasses)
I think you can buy a discount package from some nutrient companies just for one grow, one plant and that has everything you need for the full lifecycle.
Maybe the only thing you need to buy is ph corrector, depending on the water and nutes ph up or down.
Thats worth your buck, if you buy al the nutes bottle for bottle, you got a lot more nutes than you need.
Hope this was an helpfull answer my friend, if so give the answer a like.
And always keep on growing. Peace 😎
