Slegdehammer whats good to replace it? they wont ship to my state

Continuing the discussion from What to do when you have nutrient burn:


All you did was post a GrowFAQ I made.

what does as good as sledgehammer to flush the plants?

Sledgehammer does not flush plants. it is an additive that provides a higher level of phosphorous and potassium in the finishing stages. I did not look it up, but I think the N-P-K rating is 0-9-18…

thanks! for the information

I am going to try Roberts grow nutrients next outdoor in 2016 . I’m sure I will have good results . Already have it .
