Don't know if it helped, but certainly didn't hurt. I think it was exactly what I needed but I applied too late. Would definitely use it again if I ran into a nutrient issue.
I don't think I needed it at all. In fact, they may be TOO effective. Daz from Night Owl says he usually gets nitrogen toxicity using ReCharge. I think the microbes already present in the soil will be more than enough next time.
