Any Truth to Alternating Nutes With Straight H20?

Topping off with h20 or just straight h20 no nutes? I

i change resevoir every 7-10 days with nutes and top off with ph'd water inbetween..

There is much logic to this, a few sites on the web say there is much success to be had, but they're also the same sites that are selling H20 that is 'pure'.. the upside.. if it works - cut down on nute costs (even if home-brew) & nothing really 'invested' other than a crop cycle of time and more water. Downside: If it produces lower yield, you still have the same electricity bill.

^^^^^^^^^^^^^^this is what i do as well. i have hit .83 gpw with base nutes only and no co2 using this method.

i top off with 8gal H20 every 7 days, first week i hand water each plant half a cup of compost tea no nutes in res just the added H20, the week after add nutrition at full strength(dynagrow grow) for the added water. then back to compost tea alternating to the end.

oh and PF UCC is still around(not on RIU), he went to another site i believe, if i can remember what site,(he told me b4 he left) ill PM you.
