This was my first time using a reservoir usually I just mix it as I need it but I decided to give myself a break so I mixed up my nutes with 5 gallons of water and ph it to 6.3 but today before I fed my plants I checked the ph to be safe and it was at 5.7 and it took a lot of ph up to get it to 6.3 why did this happen and if I re ph my water will it just drop back down any help with this would be cool.....PeAcE

temperatures can swing ph but also just after time ph can drop or rise "not sure why" but i allways ph my water then come back the next morning and ph it again.

Probably because you need to mix your shit thoroughly dude. also expect to check your ph times at intervals of at least five minutes between monitoring. Temps swing PH but my meter auto adjusts for temps and it can still be slow on reading the true PH of the solution.

After that the onlty difference in PH is when it settles back out. Always mix your reservoir before watering. Or have a pump do it for you.

Edit--

The explanation for this is that the nutrients are generally going to sink in solution.
