Stop feeding it/them now, in 2 weeks flush her out. There will still be nutes in the grow medium. The plant needs to use it up and be flushed with just water..Trust me, ferts taste like shit. use lots of water let it drain out the holes.Wait a few days, and do it again.
But first..what strain? Look it up in strain guide..I started flushing my WW 3 days ago, and they've got 3 weeks to go.
