Is this normal

it normal for the first leaves to be turned under(curled) like this?

Yer its ok but keep an eye on it as it might just turn out to be somthing. Just don't panic dude this is ok as long as the next true leaves form right.

I'm just nervous I want my babies to be ok!!!

dude i think they got a patch for that

Its hard at first, of course you gona have a few failures at first, essential items are a digital pH meter and digital ec meter, buy them now dude. Soil is important as water. Here is a guide to soil and soil mixes as well as lime, have a read as i aimed it at the new grower, is just a basic guide i hope to modify again and again
