Too much nutrient?

is that too much nutrient ?
Maybe because i`m using Ocean Forest Fox Farm Soil in the beginning?

I would say yes, but not too big a deal. I don't do a lot with soil but I think you should flush it with clean water and then just wait. Plant that size shouldn't need any supplements.

The hardest part is the waiting. And with fertilizer, less it more.

SilverSerf is right. Young plants don't need much and I use FFOF and it's been running hot.
