u running benes?
seen alot of people having problems with hyrdozyme and ph flux
alot of pk boosters also cause a 24hr change in ph
another option is bad ph meter
if your probe is old or dried out it will give you very inaccurate and random readings
u have test strips?
How many containers? Container size? Rez size?
Is a Flow N Grow a production growing system or a style I am not familiar with?
Don't sweat the changes to much, trying to keep it at say 5.8 and every time it moves you counter just makes things worse. Your plants can take a range of 5.5 to 6.7 without much issue. So slow down and try to keep it some where between the ditches 5.5 / 6.8. Now next time you clean the hydrotron use some H2o2 let soak for a day.
Your city water may use chlorine or chlorimines. Put your nose to a glass does it smell like chlorine? or just a mild smell like a pool? If it is strong you got chlorine and need to let the water sit for 48 hours to off gas properly in as large a surface as you can get. A pail is ideal. If you have chlorimines you need a carbon/charcoal filter. Britta will do.
Peace
Some good info ^^^^^^^^^justiceman
Justiceman hit you on the first go-round--you're using tap water and munis usually add carbonate/carbonaceous (not sure which term is correct, but think CaCO3/MgCO3, both are carbonates) minerals to prevent acidic erosion of pipes. What does this MEAN? It means that the water is likely very alkaline, and that is not (just) to describe pH, but its ability to resist pH shift. Water with high alkalinity can be measured and quantified, and the result is this situation is always pH drift upwards.
It is 15,4gallon buckets w/3 gal mesh pots and res is 55 gal.
It's similar to the CAP buckets
Room staying @ 72-75
Well It's really up to you whether you want the stealth R/O or the tallboy. The tallboy is good because it doesn't waste water and it filters out sediment along with chlorine. The R/O does that plus it cleans the water of most minerals(brings ppm down to 0-10). The problem with R/O is it does not contain calcium, or magnesium so you will have to put those back in to R/O witch costs you more then using tap with cal mag in it. R/O is more controlled though and usually preferred especially for hydroponic applications. Tap water can vary in mineral content throughout the year so that means inconsistent water quality.
I'm definitely thinking the carbonates are raising the ph. Just don't let that PH rise above 6.8. Also what is the size of your res and how much water per plant do you need? If you res isn't big the plants might be sucking up tons of nutes causing a PH shift. Bigger reservoirs usually have less PH drift over time.
What kind of PH down are you using?
According to the pictures the plants don't seem to be doing anything crazy nor are they extremely deficient. I'd keep doing what your doing and see how they look in a week. In my opinion they look pretty healthy at the moment.
are you letting your nutes mix before your adding them to your feeding rez?
alot of nutes will react for the first 24-48 hrs
techaflora is the one ive seen alot of complaits about
