great help thanks for that i shall flush if ph doesnt lower by saturday. by the way anyone can answer my other question? im thinking of letting a week pass then the next weekend i will a bottle of guano and spray the plants then flower them a week after that, my question is does anyone know how to use guano along with flower nutes, i will just spray that one time then im thinking of giving it along with the watering just like nutes, or should i give it only once then and another time before harvesting? or should i go ahead and use it with the nutes? i know its early but im thinking ahead
