Not familiar with gh nutes, but I use a ppm/tds meter to measure nute solution and runoff.
If I need to be at 1400ppm in my soil, and I fed with 1800ppm, and the runoff is 1200ppm I know the next feed needs to be higher.

They have a feeding schedule you can find online - be careful to make sure you’re using the correct dosage for your medium.

For me I watch the leaves for stress and discoloration. I don’t do full strength due to how I water my babies.

Thank you! I add nutes every other watering so my next watering is just PH water but after that im def following this to try it.
