Double her pot size and triple her water<<<but just give her 750ml every day.
I might be able to give you better, more custom instructions but you would have to tell me her pot size and soil type.
either way:
Make sure you are putting fertilizer in her water each time. Use a fertilizer that has a zero for the first number; it will be called bud or bloom something or you may find some petrified guano stuff. or use VERY old manure to make tea from (and I mean very old and throughly dried out light brown stuff).
