Used chicken manure to treat nutrient problem and detected root burn the next day.I start flushing right away. the nutritents problem make plant turn even worse. Question is what should i do ? my next schedule is fushing again in another day let pot dry and then using aloe vera as root stimulator (with low dose).I grow in living soil. Pictures below.

if you flushed well, just ride it out a week or so. See what happens. It will be touch and go but I think your ok.
