Need suggestion on what to do- overwatered seedlings

So i have 6 seedlings about 2-3wks old.
I started in jiffy pellets and everything was good, lots of roots showing out jiffy pellets so i transplanted into 3" pots sept 17.(watered)
1/2 promix bx and 1/2 promix hp
I watered once and seemed ok, waited until very light pots then watered again sept 21.
Seedlings started to droop n yellow. Waited til dry then watered again sept 21.
Now theyre browning n still drooping.

So i know i shoulda added more perlite and need to fix.

QUESTION- should i ride it out n just make sure they go fully dry for a day or two before watering again?
OR - should i pull em and re-plant w added perlite? If so, do i get old dirt off roots and plant in same pots or just move to slightly bigger pots and add perlite?

Any help is appreciated
Thx

Or should i pull the jiffy pellets out n replant in better mix?(w perlite)
If i do this there will be some root damage.

Will send pics at 5pm when i get home but basically they all yellowed on older leaves(only just started 3rd set) then now getting rusty/burnt spots. Classic over watering signs.
The way you seem to be watering, that doesn't sound like a overwatering problem.
If your plants were drowning, they would be totally limp from lack of oxygen, and dead very soon after.
It sounds more like a soil issue. Are you feeding yet? Some yellowing of the cotyledon is normal, but dry brown leaves are not.
A 3" pot is way too small anyway, so I would use a 3 gallon pot as your finish pot, make sure your soil is "moist" in your 3" pot and transfer the whole package into your final pot.
Do not remove the soil from your root system, and I would feed lightly.
It seems that your soil has a lot of peat in it, which is kinda a problem because you really shouldn't let it dry completely out, (no soil for that matter), as it will pull moisture from your plant.
Also the BX supposedly has a good amount of vermiculite and perlite in it, so that shouldn't be an issue. Show us some pictures, tell us what the environment is like (lighting/nutes/temps),
and we'll get it sorted out.

So thats the weird thing, i used same soil last time.
Last grow I started in 3" pots then after i think 4 weeks i transplanted to 10" pots then to 10gal before flowering.
Rh is 65-70%, temps 21C constant.
On seedling heating pads.

No nutes at all yet other than I did mix in used coffee grounds this time. But it was like i donno maybe 1 tbsp per 3" pot.
So maybe ph issue?? From what ive read though used coffee grounds should b close to neutral ph?

I have a pic from before they stopped growing n started yellowing.

Also, this excerpt from grow weed easy is why i believe to be over watering. The last pic from the grow weed easy thing is basically exactly how my seedlings look just only starting 3rd set of leaves.

The soil looks perfect in your photo, along with your plants.
You are having this problem with ALL your plants?
Have you fed them yet?
I never used coffee grounds for a ph issue, but I think it is too early for that.
How close are your lights?

That pic was before issue. Ill post pics later after work but they look exactly like the last plant in the grow weed easy excerpt.

Havent fed yet. Coffee grounds was for nitrogen but wondering if causing ph issue.

Lights are t5 HO and t-12. Like 2 inches from plants.

And yes every plant.
The death star is affected the least but still going south in a hurry

2" is too close, back them off to 4" or 6", and forget that voodoo coffee ground shit.
Also it is definitely time to give them a light dose of food, they are probably hungry by now.
I'm feeding my 4 week old plants 700 PPM (I'm a heavy feeder) now, and their loving it.
Start at 500 PPM, that will do no harm.

Fuck coffee grounds, that BS. Back the lights off (heat stress), they actually look under watered, give them a very light dose of nutes, (after repotting) and get them out of those teeny tiny pots, the tap root will outgrow them rapidly once they start to thrive
These plant are 3 weeks old? The soil sucks or you have never fed them, which you should do right off the bat, lightly, but something.
I call bullshit on people that say you don't have to feed a plant for a month, because they end up with plants that look like yours (lol)
Oh yea, and always ph your water to 6.2/6.4 in soil.
Don't worry, with some care your plants will be fine

Ok first I greatly appreciate the help.
But...
The lights arent too close ive grown 4 strains under these lights before w them always like 1-2 inches away no issues.

Not underwatering .

Pots are fine size. Theyre bigger than solo cups n literally millions of ppl start in solo cups n do 2 transplants.

And problem is theyve been like this progressively getting worse for 1.5-2 weeks.
So no i cant just ride it out or theyll b dead soon.

The coffee grounds are mixed in the soil.

I donno man I guess ill try to feed em friday n hope for the best. FML

I am willing to learn though so ill take your advice.
I moved the lights up.
I just did a slurry test w soil n ph is like 6.5 so should be good.
I hope feeding them works lol
