Hows it going everyone? Nearing the end of my first grow and don't know much about this subject, the strain is blueberry cheese and growing medium is hydro, its from clone and had 3-4 week veg and is on 49 days flowering, i think it will be prime for harvest in about a week. Anyway back to business, a friend told me to buy some flush and just use that with water, no nutes, would this be correct or should i feed just PH adjusted water for this last period or stick with the nutrient water?
When you flush the last week or 2. When someone is referring to flushing its just saying they are using straight water, to clean all the ferts out and making your smoking better tasting.
Couldn't have said it better. Also, the buds may turn darker, but don't get discouraged by that though. It's all apart of the process.
make sure its distilled water.Cleaner the water the better non chem tasting bud you will have Even flush for 1.5 weeks if you can
Tap whater is fine to use, there is a contraversey going around with the chlorine in the water, you should let it sit for 24 hours before useing it on your plants, but ive been watering with tap water as soon as the buckets are filled up with no issues for years, it all depends on where you live and whats going into your water.
