At first I went directly from veg nutes to bloom nutes.
I started goig 50/50 for a week or so between switching,an once in bloom add veg nutes once every 2 weeks or so.
Any opinions on am I wasting veg nutes?
Same as Hamster. I also have a perpetual harvest and so have plants in all different phases. If vegging plants have had a recent res change, I will let them go til next res change with their veg nutes. But when I mix nutes again, they go right to flowering nutes.
I think it depends on the nutrient line.with cutting edge solutions.if u don't follow that feed chart and continue the grow nutes until u have established buds forming you'll run into nitrogen deficency been there done that..you use grow nutes til your plants are done stretching.usually through week two.
just if you drop the N to -0- or if (as you answered) there is "still enough" in the flower mix
I'm starting to think (learn) that a regular reservoir swap is about as important as what's in the mix.
Just because the PPM/ph is still correct, 4 week old (used) nute-bath is not "good".
