Sounds like you are doing it right to me. Those other people are tripping on their 6.2pH.
what are you on? dwc? i wonder since the plants are always in the nutrient solution in a dwc that it needs MUCH less nutes. I can't even get close to 4.5 EC.

5.8 is a good number and i always lived by that, but i'm starting to like the 5.5-5.6 range. The plants seem to flourish. There really is no need to over nute a healthy strain. I'm right around 900ppm myself and my girls and i couldn't be happier.

I grow Deep Water Cooler (DWC) style in 12gal Igloo coolers.
Wouldn't it make since to tailor your nutrients or PH to the particular stage of growth your plant(s) is/are currently in ?
For instance:
Vegetation needs more Nitrogen so PH in that range.
At the onset of bloom, Phosphorous is more important to begin flower production, so PH for it's range.
From mid-bloom until harvest, give more Potassium than the other 2 (N & P) nutrients for a good yield and PH in it's range too.
OR
Just keep the PH stable at 5.8 , if you have the means, and give more of each nutrient during each stage of growth.
Also, your PH shouldn't fall below 5.5 or go above 6.0 really.
Below a PH of 5.5 and you begin to lose Nitrogen uptake.
Above a PH of 6.0 and you begin to lose Phosphorous and Potassium uptake.
The sweet thing is, anywhere between those numbers you get everything including your much needed micro-nutrients, but not above or below those numbers.
I just started DWC last Fall/Winter and had 3 successful harvest.
I've kept a constant 5.8 PH on all 3 grows.
My 1st harvest was almost 7 ounces (Magic Monkey).
My 2nd was a hair over 8 ounces (Elite's Ultimate ChemDawg 0
.
My 3rd was a hair over 9 ounces (Neferti's C99 C2 pheno).
All 3 diff strains but it also has to do with me dialing in my set up too.
Same GH Flora Micro, Bloom and KoolBloom powder w/ PBP Cal/Mag and Liquid Karma depending on stage of growth.
And same PH.
