I'm onto my next grow. I am using Flora Nova nutrient feeding chart in the clone phase (light nutes). I also use half strength Cal-mag, and half strength Silica Blast. I use RO water too. I have not yet added the recomended amount of Floraliscious because I'm waiting on a delivery of new Floraliscous Plus.

I have a constant PH monitor. I start out around 5.5 and it naturally drifts upward over a day or two to 6.0 before I knock it back down to 5.5 or so. This has always been my routine.
My reservoir is brand new, just began two days ago. There was a slow and steady rise from 5.5. to 5.8 as usual, last night I left it 5.8 and this morning I looked at the monitor and it read 4.0!!!!!!!!!!!!!! What the hell?? The nutrient mix looked cloudy!!!!! How does this happen so suddenly? THe rez was fine then eight hours later cloudy and dropped pH!!!!!! I have never seen this. If anything there has been sudden RISES in Ph in past grows, not drops like that. I don't understand it!!!!!

I want to say that maybe it is a sudden bacterial problem but does that cloud water and drop pH? I don't use added bacteria (yet), my rez water comes from chlorinated well water and then filtered by RO. I would think that that should be sufficient purification. I use two good airstones in the rez, and temps are good.

PLease help!!! Does anyone have a link to pH fluctuation information?
