yes you can still use the over fermented rice water. The plants like the unpleasant odor of the rice water so the more fermented the better. Urine, beer,coffee grounds can also be good fertilizer
yeah, aside from ricewash, i witnessed my grandmother using human urine as fertilizer in early 70's. And i adopt this method until now. sounds wierd but effective😅👍. 1 is to 4 part solution is safe.
