The hormone that regulates the reabsorption of sodium and the elimination of potassium in the kidneys is aldosterone. Produced by the adrenal glands, aldosterone increases the reabsorption of sodium in the distal tubules and collecting ducts of the nephron, while promoting the secretion of potassium into the urine. This process helps maintain electrolyte balance and blood pressure.
it depends on how much damage your roots have. and you might need to get some root horimone
umm go to a marijuana head shop and buy some growth horimone
