Hello everyone,
I've been growing two auto flowers now for about 4 weeks now. I'm using 3.5 gallon buckets (with a 1gallon reservoir), a 3 to 1 mix of perlite to vermiculite and General Hydroponics nutrients. I started nutrients the second week using 1/4 strength nutrients and now I have moved up to the light feeding schedule on GH's website (not what the bottle says on back). Anyway all is going good, I don't have any deficiencies or toxicity and I'm wondering if I should flush my reservoir with ph'ed R.O. Water to avoid salt build up, if so how often should I flush and after I flush how soon do I return to a nutrient rich reservoir. I read somewhere that since i'm using an inert growing media I should always feed with nutrient, I'm not sure if that's true or not. Thanks!
