I too use the FF nutes, and water with the recommended dose every other watering. I adjust it as the plants tell me to.... They get plenty of food, but I'd rather underfeed than overfeed in soil anyday.

Once every 2 weeks or so i run a ton of plain PH'ed water through them (3 x container size), to help remove any excess salts and leach the soil.

They (FF Nutes) are not fully organic (OMRI listed) except for the Big Bloom and the "Peace of Mind" series - GB and TB are only organic based, and I have burned ladies with Tiger Bloom
