Reuseing nute water...is this okay?

One thing I have started doing is I put something under the pot to catch the leaking water. I then reuse it. I was wondering if that was ok. I mean I use a milk jug and after I pour it back n its only missing like a inch of nute water, it just seems like a waste to throw it out but then I think its kinda like drinking you're own pee. Can someone help me on this.

No. Its not best practice. Why not try using less solution so only a little comes out the bottom.

drinkin ur own pee? what? lol..the only problem I could see is u dont know exactly whats in there. I'm sure you could mix it with water and water some plants tho ...mj or whatever....just check the ph and ppm like normal.
