I have been using nutes every time, was making sure I'm not doin the wrong thingdo you use nutes every watering? is that you question?
if so, i would if i were you because i dont see you having a problem with salt buld up...i feed nutes every time and i use very high ppm's( no where near what you will be using) and i pay for it if i dont do a thorough mid grow flush like i am now i believe....
