I'm on my first RDWC run and I have drained and filled my system twice. Once I had some algae growth so I scrubbed the buckets drained and refilled them to get most of it out. I drained it again yesterday when I switched to flower. Each time my nutrient solution increased ~1.0 by the next morning, what causes that?
