First grow, germination wilting [+pics]

So here's the quick lowdown.

I started these without water or paper towel germination. Just bagseeds dropped in some jiffypots with some organic soil.

They sprouted within 3 days and all was well for 3 days. Day 4 I left town for 3 days and left the watering to a friend. Today I came back to this.

My first assumption was overwatering.
But he assured me that he waited till the soil was dry at the bottom before watering again.

I remembered that I had set aside two bottles of water, one with a tiny amount of nutes [dr. earth] for later in the grow, and one with just tap water that had been sitting for a few days.

Apparently after the one small bottle of tap water ran out, he just used the next[with nutes] for 2 days.

Yes, i personally know it would be beyond stupid to add nutes at such an early age. He didn't, and didn't think twice about the water.

So i guess my question is, are the nutes the cause of death?

If it is dead then yes, the nutes are the cause most probally.

hard to tell from those pics but i don't see any nute burn - droopy but otherwise healthy leaves are either over or under watering

Well, I don't think it's dead because a second set of tiny leaves has started above the first two. So apparently it's still growing.

But I just don't understand the droopy leaves. I don't want to overwater. I guess only time will tell.

So a few days later and no difference other than the 2 new leaves per plant, wich are growing pretty fast... so it's still growing/not completely dead?

The actual leaves are still really a nice green but the cotyledons are now starting to turn yellow, normal this early [1.5 weeks since sprouting]?

Any thoughts/criticisms would be great.

Thank you

i would add some hydrogen peroxide, just at 3 or 6 percent from the chemist and add it to yer ph'd water - give it a spritz on the top of the soil then back off for a day or so. i'm quite inclined to say the issues began with overwatering - even if you think you're not, you probably still are (when yer new that is

Thanks a lot. I figured it was overwatering too. Just didn't think i would make that mistake, having read soo much about it.

So how much peroxide would you say per litre/ml?

for seedlings and clones i like to go very easy on it, so i'd put 5ml of 3 percent into about 300 ml of phd water - that's just how i do it but it works well, fungus can be a big issue when it's over watered
