like above. I am used to running the Lucas method with the 3 part line, But only using grow and bloom.
Been using that for the last 4 years or so.
Just recently i made the plunge to using the Nova grow, and flower.
the issue that has been arriving since i made the switch, is i am constantly finding my PH down to around 4.5-4.7 (almost every day)
I have been using PH Up to get it back in the zone.. But didnt haver to use much ph up or down when i was using just the GL plain juice..
anyone have any insight on this?
Thanks.
my my
btw, i grow in a RDWC set up...

I have had some drops before like this but my ppm would spike usually .. Are yours really high ??
Also my water is almost 7 out of the tap so I prefer to raise my PH with that in lieu of more chems...
Calcium buildup at the root area will also cause stuff like this .. When have you flushed last ?

Thanks Cubby, yea, i didnt have any problem when just using the GH's either.
Surfinc. i was shooting for around 900 ppm. so imo that isnt high.
i use RO water from our well. ph is generally 7.2 to start with, and ppm of 20.
this is a fresh batch, and i had NO plants in the system,, and i had cleaned out the old and rinsed out first..
was just curious if the low PH was normal with the NOVA line..
and it didnt matter if i was using the grow, or bloom, ph drop to 4.6-4.8 with either.
the girls were only rooted cuts for about a month, so i don;t suspect salt build up that quickly.

.

I grow DWC (5 gal tote) and use GH 3 part (+cal/mag) and distilled water.


My pH always acts like your NOVA run. IE swing from 6.2 ALL the way down to 4.8 (sometimes) in 20 hours

I have always chalked mine up to the really small size of the tote 3.5 gallon (of actual liquid) and using distilled not tap.

It seems to me know , that after the first 2 days of PHing up to get in my 5.6-6.0 range, it is holding.. just never experienced this using the reg. GH stuff.
late into flower i have been having a few leaf issues, and wanted to see if the Nova line would correct this...
Thanks for the replies...

Hows the results ??

well i am about 4 weeks in with one lady, and 3 weeks with the Indy dom.
Doesn't look like the Nutes was the issue.. No bugs seen under a scope,
So maybe it is my well water.?

even tho it tests at 20 ppm and ph is 7.3 starting out.?
