so i flushed each plant till it fill with water and drained like fifteen times....still getting runoff of 6.0-6.2

Should i add 1/4 tsp to a gallon of water and water my plants with some of this??

Thanks once again and really im sorry for all the questions

I just want to get this problem under my belt since it seems everyone gets it at one point in their grow
