tinytoon,
That's what I do and my plants are turning out pretty darn dank and thick.
During Veg I add part A only ph'd even when I don't add parts B and C.
So far my experience has shown me that it's not an exacting science to the point where harm is done unless there is a gross mistake. I actally only have changed the rez once so far, when I flipped them to 12/12 and switched over to the flowering ratio. No saying that this is how you should proceed, but rather that DWC is that forgivable in respect to rez changes.

I'll swap again about 2 weeks before harvest to flush the nutes and make them more smokable, just ph's water...

MerryPrankstr Reviewed by MerryPrankstr on . When topping off your rez....... I have read that when peeps top off their rez that the preferred method is to top off with plain PH water untill you have added back the same amount as your rez holds, my question is when topping off would there be harm alternating between plain and nuted water? Meaning you have a full fresh rez on Sunday, Monday you are down a gallon so you add Plain PH water. Tuesday you are down a gallon so you add a gallon of nuted water. next topoff you do plain again and so on until end of week or 10 days Rating: 5
