Howdy tyler_hobbyist,
What kind/brand of nutrients are You using? I'm using the GH Maxi series (dry Grow and Bloom) with the GH Liquid KoolBloom, Floralicious Plus, Armor Si, FloraNector, and Florashield. I do get some sediment in the reservoirs, but it is very little. There will all ways be sediment if One uses mineral supplements ( like Armor Si and/or CALiMAGic) because they are not as soluble as other nutrients and easily precipitate out of solution. This is one reason that it is good to flush the system out and/or regularly add plain pH'ed water between feedings to prevent buildup in the system.
Good luck with Your grow.
