im think of flowering my 4 girls there 5 1/2 weeks in to veg. and between 8 to 10" tall and doing well only had one brown edge. my ? is should i flush them with fresh water for a week or before i flower?
According to my fert chart (which i use fox farm) it says to flush before i flower. Guess it depends on what you use and how often you have been flushing them up to this point.
