That's a great question? I'm not sure if there's a gold standard to testing PPM runoff, but I like to see it no higher than 200 PPM more than what I pour in
Edit: 900 PPM is really high for a plant that size! I might feed 900 PPM to a large plant in full bloom, but a plant that size I wouldn't feed over 500-550 max
