Im 3 weeks before harvest and I usually flush the last 2 weeks before harvest..I just checked my ppm run off and it’s in the high 1300’s the question I have is the nutrient that’s in the soil good or should I keep feeding my plants for one more week or just start flushing for 3 weeks will the plant take in the nutrient that’s already in the soil If I just give them water? The plant in the picture is day 45 it still have a lot of white hairs

I do the same thing as @mwhite9829 ... Your PPM is actually in a good range for the week you're on. With plenty of white hairs still there i'd keep it growing.
