some leaves are wilting down but seem to keep growing?

i use miracle grow garden soil. i have the temp at 75, i ph my water. have two leds running and two fans. i leave the lights on 24/7

I would say overwatering

What do you pH the water to? How often are you watering? How much water are you giving each seedling each time? MiracleGro isn't the best stuff to use because it has time released nutrients in it.

I definitely concur.

OP, next time start seeds in much smaller pots. It's way too easy to over water in too big of pots, especially for a new grower.

For now, let them dry out, and when you water, don't saturate the pot. Give about a litre only each feed, and don't re-water until the soil is dry about two inches down from the surface. As the plant grows, continue to give increasing amounts of water. You want to get to the point you have runoff, but runoff now would mean way too much water for those plants.

Easiest way to get used to watering is start off in solo cups, or half-gallon pots. Put dry medium in an extra pot, and set this in your tent. Every day, lift each plant, and if it feels really light like the pot with dry medium and no plant, it's time to water. Water until there's some runoff. Repeat.

i water when the soil starts drying up, i have a moisture meater. and i ph to 6.5

These have had a rough time, it would almost be quicker starting some off again than nurse them better.

Whats killing them all, fans pointed at them or using ph up/down in soil (totally not needed) or something else? Whatever it is should be obvious and see them take off once solved.

Small or big pots your doing something universally bad.

some of them are doing amazing! i only showed the sick ones. and the fans are pointed in their direction. but not like tipping them over

and i use the ph in the water that i water them with, because i have well water and the ph comes inn at almost 8

Yes, but how often is that and how much water are you giving each plant when you do water them? Those moisture meters that you put in the pots can be very misleading unless you measure the level in 4-6 different spots.

usually once a day, sometimes ill just spray the top soil if that dries up way faster than the bottom soil. and i put the meter in every bucket i have, i like to check em all

Then you are probably over watering them. A seedling that small should be able to go days without needed any water. In some of those larger pots they can go a lot longer.

Your irrigation seems wrong, could be you need to move fans futher away and i would stop trying to adjust ph in soil as nobody bothers with that and your making soil a lot harder than it should be.

so adjusting ph is only for hydro? so many people have told me to make sure the water i use to water is phd. this stuff is so confusing

Adjusting ph isnt only for hydro, its just much more sensitive than soil would be. Yes soil is a natural buffer but you would still need to ph if your water is at 8, especially when feeding anything. My water is 8.5 out of the tap and have issues if I dont adjust.

This is absolutely correct. It doesn't matter what medium you're in, you have to pH your water (and water/nutrient mix) correctly. Hydro, soil-less and soil all have different pH they require before feeding the plants.

Soil is definitely the most forgiving, but if you're not consistent with pH going in, things will eventually go sour.

The problems caused by bad pH are severe. You can see all manner of deficiencies and toxicity of several nutrients, all simultaneously. Some of the damage will be permanent, some will recover, but you have to act quickly or it will be fatal.

Best way to avoid these problems is by feeding properly pH'd water.
