yep, my seedlings are acting weird I got a few pictures of the one that has it the worst.








As you can see one of the leaves is already dieing, why is this? Do I have my lights too close? they are 3-4'' away from the seedlings.

What kind of light are you using? Your soil looks like it's loaded with wood chips which is bad for the roots, especially developing seedling roots.

OOOH I missed the big pics (blonde had fire wall on high) woody soil, wood holds moisture moisture on roots causes root rot and that yellowing of the leaves. Risk a transplant to real soil or they wil die get all the wood away and get real soil add perlite plant em HOPE and PREAY

I sterilized some soil from outside by baking it for an hour and mixing in some miracle grow potting soil. I have a 42 watt cfl and 2 27 watt cfls on each side of my two plants. I have been supplying them with direct CO2. I have had to water it twice a day because the lights dry out the soil to a point where all of the soil the root of the plant occupies is dry.

The Potting soil is better than the outside if that was the outside with the wood.
Perlite is cheap and it stops soil compaction, and allows roots to get oxygen

No it can't be the soil or wood because I had another plant in here for 3 weeks before it got fried by a loose light. That plant was nice and green. Also my potting soil has tiny wood pieces already in it.

I said the same thnig but then I tried MG Poting MIX and Perlite 50/50 never had a sprout problem again, and I killed like 10 of em before figuring it out.

I think the co2 is a waste before the first month has passed. You shouldn't let them get so dry, I always make sure there's a little bit of moisture about an inch down with seedlings. You might move your lights and see if they start to stretch, if they do move them closer again. Try using just the 27w lights if you can, the 42w light probably isn't helping much while they're so young, I keep mine under 13w lights for the first week. Good luck, I'm out.

Transplanting will be easy, I have them in a little germinating peat moss thing and the root hasn't come out of that yet. That stays constantly wet since it was made to retain moisture. I added alot of perlite to my soil and it has gotten alot fluffier and looser, better for root growth.

Peat also raises PH. Check PH of water run off after it filters through the soil. Chlorine can kill too let water stand out for 24 hours if not already doing it. One of mine that did not make it

I use filtered water the ph is alwasy at 7 and there is no contaminants. not even chlorine.

I'm going to leave her out in the sun to let her get some natural fresh air and sunlight, maybe it'll make her recover better.
