I use a slightly different grow method as you but I mix RO/filtered water with tap, about 50/50 or 40/60.
I didnāt read if you checked your starting water, but when the ro filter goes out its supposed to increasenreadings

You can also fill your tent with one giant organic soil bed as well and stop using synthetic ferts.
For example: BeagleZ Corner
I wouldnāt use all the amenments he does though, Iād install a worm tower in the middle and keep filling it up with a wide variety of kitchenscraps, that provides all minerals and nitrogen.

Diff nutrients get utilized or not within a ph range depending on where it falls. Theres a chart somewhere (complete) Kashmir- A place for my Freaker grow - #360 by George
From the post before that chart it seems some people recommend a 5.8-6.0 ph for coco during flower. Reading just a bit more others seem fine with your 6.2.
Iād probably trying lowering, but your plants definitely dont look bad and Iām sure they will finish strong even if you donāt change anything

yeah, i was recalling when I first switched from hydro to coco, i was told that i should change to soil ph zones, but it was just clarified to me that is only when running coco with an organic setup. using bottom fed salts I was advised to target the range you mentioned, so I adjusted the res, and last reading was 5.78

So a EC of 1.3 is roughly 700 ppms depending on pen manufacturer which seems low to me. What brand pen you using?
I have much much smaller plants in veg that I use 7-800 ppms for.
Stick it out man they will come along.

This is the pen I use, and yeah, it is low at the moment because the last 2 fills were a massive jump from super low feed, to jacks 4-2-1, then worrying that the jump was too much at once, so I dropped in 5 gallons of plain phāed water, to bring it back down.

Iām letting the plants simmer today. Once the reservoir has about 1/3 to 1/2 available, I think Iāll mix up some jacks around 3 - 3 - 1.2, and slowly build up to that through the next couple top offs.

The close one on the right side, and back left, have a lemon pinesol smell if I touch the buds.
The close one on the left does not really give me anything, just yet.

thatās great. i think the lemon pinesol comes from the OG in the chem fuego cross, [(sour diesel x OG kush) x chem 91]. iām glad that scent is showing. i kept hearing how nice the " lemon" is, but i donāt know if they meant lemon pinesol.

The one on the right, 100% reminds me of cleaner, more than a candy smell. I will check the back left one first, next time.

I definitely had a sweeter version of the lemon. It wasnāt so much cleaner as it was a lemon head candy but very strong.
Pretty cool to see variants.

Im also terrible at identifying smells, and could be just creating unnecessary confusion

Nah I recall someone from the thread mentioning a cleaner smell as well. Canāt say whether it was pledge or pinesol lol one of them lemon cleaners!
Maybe though since covid I feel the old schnozberry doesnāt work the way it used to.

Pledge might be a better cleaner to use. I didnt smell pine so much, as lemon cleaner.

Must be nice my friend. Must be nice. lol
@other_barry on the plant side of things I really think that tent is not bad at all right now. That last picture you just posted the right side of the tent is looking pretty gorgeous. The other two are just a little light. One of my BBDs was finicky maybe you just happen to have two lol
otherwise itās looking like a damn decent run dude. I think you were being hard on yourself lol
