To flush or not to flush?

Depends on how you're growing @Noahbear If you use organic nutrients you probably don't need flush. Just feed her water the last few times and you're done. If you using organo-mineral or mineral nutrients you should flush. You can flush by watering with pH 8 water for example as the plant won't be able to absorve the nutes and they'll drop with the water. (pH 8 water is obtained by adding some alcaline substance to the water like pH+ products) If you using 100% coco or any inert medium it's easier to flush as the coco is way easier to clean and cannabis in coco are grown with runoff on every watering. If you want more pointers we can always chat ;)
