I just switched to AN from Botanicare PBP. Because it was a new setup, I had some issues in the beginning of my grow (my pH was erratic, not enough DO in the water, temperature issues, not to mention the nutrient switch, etc.) So, while my plants were still having a decent amount of new growth, they were definitely getting some yellow/burned edges. I bought a bottle of Revive yesterday; I'll keep you guys posted on how it works. (Here are a couple of pics what some of them looked like yesterday)
