Water is hard ... EC runs at about 0.5 - 0.6 out of the tap.
I've also been feeding CalMag @ 1.0 ml/l in the waterings I have given ... just to be sure.

Due to the small rust spots, it almost makes me guess a calcium deficiency. Doesn't look to be over fed or have N toxicity, they're a nice green. What cal/mag are you using? What's the NPK? I usually run mine around 2mL per L.

Ok i went back over your last grow ....it was a blinder, so i wanted to see if you had changed anything. the last grow at this stage they were getting.... B-52, Carboload, Bud Candy, Pro XXL, Voodoo Juice, Sensi Grow A + B ... all 1ml/l
Which means this grow they are getting around 3ml less of the magic ingredients you were feeding in the last grow.... Here in may lie the problem...What you think?

That's what I was running, but it's heavy on N. I switched to General Organics Cal/Mag that's 0-0-0.

Could well be a factor.
I was trying to dial back on the nutes this time, but maybe its not such a good idea.
Hmmm ...
Carboload and Bud Candy are essentially the same, so I can just double the Bud Candy.
That's an easy one to fix.
B-52 might be a good one to bring back in.
Voodoo is essentially for the roots, which might be good for the transplant stress, when I get around to doing that.
So you think the discolouration is from UNDER feeding, not OVER feeding?

Just a thought ... the other obvious difference from Grow #1 to Grow #2 is the pots.
Could this have anything to do with the root mass being 'bound' or not having the additional oxygen/airflow that being in an airpot would give them?

your way and subbing up hope it all works out for you

DAY 23:
Temperatures: ... Ambient Room 25 ℃ [+/- 2 ℃]
Humidity RH%: ... 45 [+/- 5%]
Lighting: ... 2 x 600w HPS
Schedule: ... 24/0
Nutrients:
pH of Feed: ... 6.3
EC of Feed: ... 2.3
Feeding: ... ~ 1.0L
Feeding today - overdue ... the girls were looking limp and haggard.
No pics today - I have to get my head around the issues in the tent and the best course of action to take.
Only way forward I can see is to 'start again', with fresh soil and fresh pots.
Not what I saw in my future a week ago.
The really annoying thing is that for the most part, the plants are looking green and healthy.
It's just these frustrating issues which seem random and only affect the small minority.
Which I guess is also a good thing. At least its not all 16 ladies!
Either its some funky assed genetic variations, OR its something as simple as the ones that got the older soil are having an adverse reaction to it. By old, I mean from the previous grow - not recycled - still in the original bag, but somewhat drier. I guess given soil has organic matter in it, its prone to oxidation/reduction, which could throw some less than optimal pH into the mix, so it does kinda make sense. Fresh soil and repotting would easily and quickly fix that.
In my head a logical explanation would be ...
It's the most simple explanation and also explains the multiple issues showing up on just a few plants.

In the Infirmary thread @Waira keeps telling me to get a pH Probe for the soil, to measure exactly this point.
If nothing else, I am learning A LOT from this, and the importance of the medium, which I never really took notice of before.
I was pretty much working under the [naive] assumption that as long as you control all of the above ground factors, a good commercial soil, that comes recommended, will take care of everything under the surface ... and I guess in the vast majority of cases, they do.
Another grow, another day, another lesson.
