I have 2 bubbler set ups, 1 of which was at about 70ppm for the first week, the 2nd of which has been at about 100ppm. The 2nd plant has been growing slightly faster. After researching and buying my tester, I've adjusted the PPM for both set ups to about Currently, I'm at just over 100ppm for both of my set ups and the plants have been growing fine, they are a BIT slower than my soiless mix, which is making me wonder if I should throw some fertilizer in the bubblers and adjust the PPM? Or, should I do it at a slower place, like I have going from 70ppm to 100ppm.

Thanks!
