Bottom half of plant is sad

Not sure what to make of this. The bottom half of my plant has been droopy for week. It gets the same PH and PPM as the other plants. It is the fastest growing one. And other then it drooping has showed no other negative signs. Any ideas? I am running Roots Organics soil, 2 600w HPS in a 4x8x7 tent. Temps stay in the high 70’s to low 80 with humidity around 40-45 percent. Water is ran threw a small boy PH is always between 6.3 and 6.5.

OK. Imho.

The size of the plant has quite a story to tell.
If it's been feeding the same, and growing faster than the others. Then it has more roots too.
Plants that are in pots too small, will droop. I realise your pot isn't too small. But you're not using your airpruning pots effectively.
The bottoms of your pots aren't in the air. It's dark, and wet underneath. The plant thinks there is more soil, and is shooting new roots down. You need to sit the pots a couple inches in the air. So the bottom prunes as well.
Usually plants in small pots, start to suffocate, when their roots hit the container. Then they also start dropping older growth to compensate. They get nutrient deficiency as well. Even if there's plenty there.
My advice would be to add a tray with lots of drainage holes that your pots can sit on, to get airflow underneath, and start airpruning.
Some of your fans look magnesium deficient as well. Keep an eye on your other plants. If they start to show magnesium signs too, hit me all with some ebsom salt.
Otherwise if it's just one plant. I think it's just your pot.

As far as how the pot is that’s a awesome idea and I never thought of that. But they have only been in them for a day or two. Just transplanted from 1-5 gallon. 1 gallon was black pot. And the plant has had these Simptoms for weeks

A few things that can cause bottom growth drooping..

-lack of light penetration

-underwatered

-you water too quickly, causing bottom growth to sit in a puddle

-primary deficiencies

-moisture/environment stress

Suppose we can widdle that down to only a few considering it’s the only plant doing it. And I have another of the same strain with no issues

OK.
Changes things.

If your others, are truly fine.
You only transplanted a few days ago. Leave them. Let them all settle. Dry it out.
Treat the large one separately next feed.
IMHO feed it the same as the others. BUT just for the large one, supplement a little ebsom too. See if it perks up.
If the plant is bigger, same pot etc. I find it hard to believe it's a watering issue, if the smaller plants are fine.

It's probably a little shocked from the transplant too. Just give them a little to settle in.
Then try and narrow down the cause.

It's a larger pot too. It might be worth checking the pots aren't too cold at lights out etc.

Yes just transplanted but had this issues for a few weeks. Currently I’m not feeding anything, haven’t seen any signs telling me to.

Yeah.
I'd just give them a little time.
Maybe dim the lights a little for a day or two.
Then don't change a thing for the others. But start treating the droopy one from their next feed.
Try to find what's going on with the big one. I definitely think it's size has something to do with it. Whether it be a root issue. Or that it's deficient because it's eating more than the others.

Those are just a "few" things that can cause the under-foliage to droop, not saying thats the problem.

Fwiw, its usually the biggest plant that hits its limits before the others.

(E.g) if you water and feed all plants on the same exact schedule, you will end up with your biggest plant being underwatered & underfed which can droop the bottom of the foliage.

(E.g) at 35 watts/ft2 it wont be hard for the underfoliage of a trained plant to get lost in the dark. Alot of dudes just pluck off the bottom of the foliage, other dudes just spread them out hell sometimes people say fuck it and let it droop.
