Read his comments. He's using a pH pen to determine he has a pH of 10.1 lol.

"Sodium Hydroxide is Basic

At concentration of 1 mM, it has a pH of 10.98"
I mean, alkaline drinking water is ~9, and 10.98 is almost a whole order of magnitude greater than where I'm at, but again I'm totally willing to believe it's wrong. I'm just telling you what the results are saying.

Hey all, really need some help here, never had any issues like this :(

They're all on day 12 after being placed in soil. They're both Ethos, 2 Original Mandarin Cookies (first two pics) and 2 Planet of the Grapes (pics 3&4)

I thought I had this all taken care of, I got my new pH meter and realized the tap I was watering with was INSANELY high, so I was like oh yeah that's an easy fix, so I've watered them twice since then with 6.5 water, runoff is in the same range, but they just seem to be getting worse :( Idk what the hell I'm doing wrong here and I'm starting to feel bad for these lil girls.

I'm in a 4x4 Mars Hydro tent with Mars Hydro TS3000 and AC Infinity T6 fan/filter/controller. Temps range from 68-74, RH ranges from 40-60% (only goes below 50% when the humidifier runs out, and the AC Infinity controller notifies me when it gets too low so I always refill it pretty fast)
I'm in 7gal fabric pots (transplanted from solos when 2 of the four had roots sticking outta the bottom of the cup) Coast of Maine Stonington Blend with 20% added perlite and a small amount of Espoma lime.
As far as nutes and stuff, all I've used so far was a tiny bit of Recharge when I first put them into soil, and a small drink of Fish Shit (2mL /gal) on their first watering in soil.

If there's any other info you need, just ask. Any help will be very much appreciated.

Nobody has mentioned it yet so I thought I would.

What % is that TS3000 on and how high above the seedlings is it?

Next time go longer, until a semi substantial root mass builds up, as per this image. It's the reason to transplant, not just to prevent overwatering but to benefit the rhizosphere's development.View attachment 5045291
Makes sense of course, but I did it the same way I've done it every time before and never had any problems with transplant shock or anything like that so why would it just happen this time? This is my first time with Coast of Maine, I used to use Roots Organics so idk if that has something to do with it.

As far as all the diagnosis guides I've checked, it does look most like pH fluctuation damage, but figured it would have started to improve by now with the water being adjusted. Am I just being impatient? Like how much time should it take for a pH issue to resolve after you've essentially "fixed" the problem?

The light would be my first guess, easy to cook seedlings with LEDs on your first grow. If you use municipal tap water, check your online quality report to double check the PH. Every dinky town in the USA has an online report. I live in a town of 100 people and found mine with a bit of effort.

The lime added to the soil is just making things worse.

Honest question, why is everybody adding lime to their soil?

i use coast of Maine and perlite and don’t add anything to it until like 5 weeks.
