Flush nute solution frequency.

in a bubblebucket (DWC) is there a downfall to flushing (dumping and resetting the nute level & ph) too frequently? Other that the cost of nutes?
Will the plants suffer some kind of shock?

My blooming Magic Bud is quite hungry and i wonder if flushing will help the buddding, bud.

much appreciated.

What's up man - Bro, if you can afford it, DO IT! I believe, as long as your nute levels and ph are right on, and your plants are responding well to those exact levels, giving them fresh and balanced nutes and water more often can ONLY help, not hurt. PLUS, and this is especially true for DWC systems, giving your root zone some time to breathe a bit will help more than you know!
You should ABSOLUTELY check out the posts on the Stealth Hydro Bubbleponics system in general, but in particular ROSEMAN'S threads and all his advice. The Bubbleponics system is basically a DWC tub (standard tub, airstones and air pump) with the addition of a top feed/drip system with seperate lines feeding water to each plant. Any advice I give you is ALL from reading through this site, and especially from the Roseman. REALLY cool dude; I'm sure he'd be more than happy to give you some more specific advice. As he'll tell you, even draining the water, giving the roots some air, and adding back the SAME water will help quite a bit! Best of luck to ya man, PEACE
