Burmeseanswered grow question 5 years ago Hey buddy, flush with pHed water 6.0~6.5 with 0~40ppm water.If you don’t have enough water,flush until what is in.Means flush until runoff ppm 0~40 and pH 6.0~6.5.If you already watered 2 or 3 days ago, leave them for now.And start flushing when top inch of the soil feels dry.If you are using about 5L of water at each watering, I think 20~25L per pot would be enough to reach flushing ppm.Dont give up man.You can control in time.Happy growing... ✌️
