FIRST Grow -Seedling problems

Hello all! First grow here. A little info to hopefully help. My seeds are big kush in a soil perlite mixture. The soil is organic Fox farm. Running 18/6 600w LED. Proper drainage , 60% constant humidity , 77f lights on , 69 lights off. It’s been just about 5 days since watering because I feel I over watered them. They aren’t crunchy or showing signs of needing water, drainage is good but soil still moist about a knuckle length down. I’m worried I messed up and won’t be able to save them. Any help would be appreciated! I attached a photo for reference.

You are doing fine. Don't water until soil no longer feels moist when you stick finger in. Over watering causes all kinds of issues.

Ok thank you! They are kinda dry today, still showing serious signs of over watering on most. I’ll leave for another day.

Watering was something that was problematic for me.
New growers don't realize that different plants at different stages of growth are going to take different amounts of water.

For instance: a small seedling or plant in a ( relatively) large pot. I used to soak the entire pot, it would take for ever to dry out. The small plant can't transpire that much water, so you are waiting for soil to dry on its own thru evaporation.

Now I water much less, but only near the plant. As the plant grows, (and starts to use more water) I use more water, and direct the water further out to edges of pot.

Good luck!

... later you can water your plug but... if you planted in an oversize pot, water the outside rim, so the roots search for water. That is what makes healthy roots.

Furthermore, if you have somewhat moist soil, 1 cup (8oz) is all you need for seedlings (in a 5gal pot). I like to water every 3 days. I use a moisture meter and pot weight. W D D F D D W, Where D=dry, W=water and F=feed

Thank you for the replies guys! I am receiving a scale to weigh and a moisture meter today actually! It’s just odd that they are still showing signs of over watering even though the soil is drying out. I guess another light cycle will tell!

Ahh. I'm doing it backwards? I try not to water directly on stem to prevent stem rot, but usually closer to center than the rim.
I'll try it your way on some.

Thanks Switch.

Oh wow! So I am over watering for sure then in my solo cups! A cup to 5 gallon is not what I thought. I have got to figure out the water situation quick.

I grow in HP Promix. I use jiffy plugs to pop my seeds, after germination in paper towel. Then, I only spray with H20 to wet the plug. After 1st serrated leaves appear (tghe roots are at the bottom of the plug sneaking out), they go into a 4" pot, where they may get a couple of ounces (dunno). I transplant in 5gal pots at week 4 in veg.

I water or feed at a rate of 1.5l every 3rd day, always starting between the stock and the pot rim, finishing with the plug.
