Jim, dude, you were doing super well up to week 5/6 (i would say 5 because of latency of symptoms)...
After that you started getting serious phosphorus, calcium, magnesium, sulphur sort of issues....
And obviously, I can't say why that is really. But it looks like excess, maybe something specifically acidic causing lockout (which acidic factor, I wouldn't know though). I'd recommend you kinda go more neutral at around week 5.
That plant up to week 4-6 looks stunning, so don't change much about that. Like the peak balance there was probably around 5 weeks. For shit after that, you might wanna change your method a little bit.
And I don't say this to be an asshole, I just figure you can always grow shit even better.
But then again, looking at the vegging...it might have even been hormonal effects a bit before that, coz 3 weeks vegging seems kinda low.
Edit:...
Oh sorry, I didn't notice it was pretty much an auto (coz the name doesn't mention that)...so I checked it out. And now it makes sense.
@Jimbud,
For like sort of mid-veg though, shouldn't you use a bit lower pH, I mean roots would be mostly established? And phosphorus usage for instance then, is fairly low relative to to some other elements.
Like the plants clearly have a sort of maturity/seasonal bias, elemental usage at the time, etc.
But hey, I've never even used pH testing, whatsoever.
@sir_isO, Just started a 3 Bears OG Gonna go 18-6 in a closet grow for the summer My PH 6.4-6.8
Getting ready to put my Photo’s outdoors after this Holiday.
@Jimbud,
Btw, was your pH 6.5 throughout?
Personally, based on speculation, I figure just around 6.4-6.5 is ideal at start and finish. Coz obviously the flowers' purpose is to try make seeds...and phosphorus then gets loaded. Like a phasic thing where flowering and germination/rooting is kinda similar, with a drop in ph and bias with nutrient utilization between that.
