Need to get rid of this problem. Could be root rot/pythium... DWC EXPERTS PLEASE HELP !!!!!

@Hollatchaboy do you know a lot about DWC/hydro?? Plant was a clone and was fine for 3 years and went bad with the above issues.. Other plants in other tents having higher ph issues that get stuck at 6.3 and won't come down, but still drink and turn out fine... Why else you a plant stop drinking all of a sudden??? Like I said this plant is about a foot tall from clone and pulled this act of not drinking.

I've grown dwc for a couple years, but I don't break it down like a lot of guys do. I've not had problems, except with feeding. Then I was turned onto the Lucas formula and I've not had problems since.

Your plant isn't drinking, so the ec stays the same also?

I refer to this as the "Wonderchart" because it just make things so simple.

"Son of Wonderchart" is attached. This one is for plants that are taking up water. There's another one for rare situations when plants aren't taking in water.

When I add an entry to my journal, I use a three letter code. FSS is Falling water, Static PPM, and Static pH. Creating an abbreviation is a really good way to portray the state of the res at any one point in time.

Oh, yeh - like so many other things, these are guidelines and, the part of the Wonderchart that talks about lowering EC until pH stops falling is just plain wrong, as I found out. After my second grow I learned that it's common for pH to drop in hydro when going into flower. That was a hard earned lesson.

My pH only drops in late flower, when she's almost done. Otherwise I start at 5.4, and it drifts up. I usually let it rise to 6.3 - 6.4.

Only 1 of 3 strains isn't drinking and yup the ppm/ec stays the same and the ph is always around 6.3 no matter what I do.... The other 2 strains are drinking and growing fine, but the ph gets almost stuck at 6.3.

Yeah I start at 5.0 and she drifts up to 6.0 over night after rez change.. This whole thing is wierd.

Now I have another plant NL x big bud and its in its own tent/rez and its fine the first 35 days of flower.

That's great. You're covering a wide range which gets good absorption of all of the nutes.
