not a hydro guy,but by reading this,im thinking if you change your res weekly,just adding the ro water alone would be a ph down,i got baked last night but from your question ,seems your going wrong direction with your ph down,going higher more than lower,hydro i would asume stays as the start res feed was and loosing ph and ppm from just use,of time and plant thrive,i guess what im thinking is,just adding water,and cal mag would keep those numbers correct,i see this all the time when temps start to sore from summer,and most cure problem with added equitment for cooling the res,not my gig for sure,i just thought something was wrong with my eyes as you explained your issueHey fellow farmers
My question is , I run R/O water. My nutrient base ppm with everything is 880ppm. I add my ph down and it brings my ppm to 1110ppm now I'm using the resivor for a week 5 gal res. Everytime I adjust the PH the PPM raises. I know I'm not adding nutrient, but my question question is if I keep adjusting the PH every feeding throughout the week. My ppm hit 1300 or a little higher by the time the rez is finished. Is that normal? Is that ok? As long as I know what my base nutrient levels are ? How do I know how much my plants are eating if the ppm never drops because of the PH down I'm adding ?

Sorry sorry. I was driving and I had my wife reply for me. I have 2 threads going on different but similar topics. Yes it's only 5 gallons. It's feeding 4 inch rockwool cubes. I only to light feedings. Feed 2 timed a day . Lights on and 3 hours before bed. 5 gallons.In the original post you said 5 gallon.
Then lower your beginning nutrient strength. 880 ppm would fry most of my plants unless I'm saturated with light and running co2. Also would recommend going light on the silica as the plants don't really need a lot of it and it's a base so it raises pH.Running veg and bloom nutrients , life plus , cal mag, silica and mammoth P.
The ph swing is only .5 from 5.5 - 6.0 which isn't bad but I notice it adds ppm. If I can use the same 5 gallon rez for the week but by the end of the week there is only 1 gallon of nutrient water left. And the ppm is high from the daily adjusts up to 1400ppm. I don't let much run off maybe 10%

These are my thoughts. Nutrients are nutrients ph up and ph down are not nutrients they are adjusters but act like fillers. I don't think that you can over fertilize or burn your plants from adding a ph adjuster to your base nutrient because it's not a nutrient. It just takes the remaining space in your ppm range to adjust your nutrient solution. Does that make sense ? So if my plants are eating food and I'm filling that space that the food was eaten with ph down I wouldn't be able to because there would be no room in the ppm range I want to stay with. Any pros want to comment ?
First you're using RO water and as such it has less ability to buffer or stabilize pH. Most bottled hydro nutrient contain pH buffer in them already.
PH up and down can seriously effect your plants if not used properly. Both are corrosive and should be handled with the proper protective equipment when handled.These are my thoughts.

Agreed, I grow in soil. You hydro farmers got your hands full monitoring your grows! That’s fer sure!!Correct I agree 100% I have followed the rule not to mix them together in the same rez and definitely never let them come in contact with each other in consintrated form! Use one of the other and if your not patient enough and you let your ph drop or spike to much and you have to use the other adjuster as well to correct then your asking for major fluctuations ?
