hillmananswered grow question 4 years ago At this stage autoflowers are very hungry. Up the nutes consciously in the next waterings. Normally every third watering should ideally be just water, but you are running out time so I advise this: water every other day using plain ph-ed water first, then the nutrient solution. This will delay the salt accumulation and improves the quality/taste and the amount of nutes availlable. The plants will love it. Pottasium, nitrogen, phosphorous. Thumbs up!
