I personally would reduce the vinegar instead of stopping it. As Randy mentioned the bacteria will reduce their population one or the other way.Going to hijack this thread a little. Randey Holmes-Farley or anyone else with like experience. I have been vinegar dosing for over 2 years. I have great growth and my oranges and green and purple colors are good. Not really pale at all. By pinks and reds have pretty much gone and stayed tan/brown. My last few ICP test come back normal for trace elements. I do dose iodine, strontium and Kaladium to keep those normal. My Nitrates have been running 1 on various tests and phosphates vary .00-.05. Usually around .02 for the most part. I stopped dosing any vinegar for a couple days to try and raise nitrates up a bit. My goal would be 5. Is there any harm in stopping vinegar cold turkey?? I have seen skimmate drop off but no movement in nitrate or phosphates. Not wanting a huge crash all the sudden due to stopping vinegar.
I found it's easier to adjust carb dosing down and observe where Nutrients ending up at, instead of stopping it and basically figure out again how much to dose daily to maintain a desired nutrient level.
What I've done also is to increase No3 and to avoid dosing nitrates, is to add filter fleece into the socks! Those are No3 factories after a while and lift up nitrates too.
It's a bit tricky to find the best balance of Po4 and No3 reduction with your carb source.
Vinegar I feel the Po4 consumption is better than with certain other carb sources.
Maybe that is another option you haven't thought about.
