I am attempting to play with hydro and have two DWC buckets going in veg. After mixing the nutes per the laben on the bottles 3-2-1 tsp per gallon I get a PPM reading of 1800. the water starting out was at 90PPM.

Everthing I have read seems folks keep thier PPM alot lower. I cant even messure it after I add Liquid Karma and Epsom Salt.

So what the heck am I doing wrong here?? I have 4 Gollons of solution in each bucket and make them individualy. Thanks
