YO!! Anyone have PH not raising to neutral problems in Hydro/AeroFlo?

So im in 1st week flower and just this week my PH stopped neutralizing like it normally would. In fact, it would lower (get more acidic). Is this usual? I used advance nutes has anyone else seen this problem?

I tried a full flush 24 hours ago. Now I'm going to try hydrogen peroxide flush.

Thanks for the feedback if I haven't already figured it out.

i think your ferts are too high in concentration. try and flush the res with plein water

I don't really understand what the problem is. I have 3 aeroflos and use advanced nutrients also. Keep your ph at 5.6 (as recommended
by AN) by using ph up or ph down. Why would you feel the need to flush? Or am I missing something here?

when ferts are too high usually it results in lower ph and nute lockout, when nute level is normal ph drifts UP slowly

Zem, yup, this is how it should be.

I fixed it the first time around just by flushing. I actually ran into the same problem again a few days ago, and flushed yesterday. So far, no bueno. I'm going to flush again and see what happens tomorrow. I've also found that my humidity is freaken low right now and I know in flowering they don't like dry air... So I'll be adding a humidifier (never had a humidity problem before but this winter is just dry) today.

yes, zem to many nutes, it is better to under feed and move up slowly than to overfeed. These plants can handle a lot of nutes if dished out slowly but I find the fastest growth is at about 900 ppm for me.

get a new meter and double check. And for gods sake stop flushing!
