I use GH floral series, if my PPM is too low, is it safe to keep increasing the nutrients to bring it up to recommended amounts? GH recommends 350 - 400 ppm for seedlings.
After adding the recommended nutrient amounts of 1/4-1/4-1/4 (teaspoons per gallon) for seedlings, ppm was just under 100. Since they are at a delicate time in their life, would increasing the nutrients be dangerous?
I wouldn’t increase it, I would only feed if you’re in a medium with no nutrients.

You can go 250 in dwc for small seedlings. That’s what I use. That’s when they have leaves with 3 blades or more. Stay lower until then.
