For now that will work, you can start increasing ppm as they get a little bigger.
Sounds like bacteria or algae building up in your water. I change my nutrient solution once a week and I use an enzyme cleaner called Z7. You can use Hygrozyme, sensizyme or something similar to keep your water slime free. Keep your buckets as cool as possible to slow down or prevent the slime. It happens, you’ll get this going just don’t get too bummed.
Shouldn’t be Z7 or hydroguard causing the foaming. What else are you adding to the Rez?
Try hydrogen peroxide in your Rez to kill any bacteria or fungi.
If it’s 3% just use it as is.
