So my grow has taken a turn down the wrong road. After changing out water last night I must have added too much nutrients, which in turn has left me with fried leaves and some brown roots. What can I do to clean the roots? I've heard hydrogen peroxide.. I recently just flushed with ph'ed water and hygrozyme..
I would just stick with the hygrozyme and flush for a couple days, then resume light nutrients. If the damage stops progressing you can start raising the ppms again. Sorry to hear about it, but it happens to the best of us.
damn dude thats a shame. Ya i have a buddy that uses hydrogen peroxide and it works pretty well. You only need a very small amount tho! Good luck man hope they come back!
