seedling issues! help!

I have 20 easy ryder seedlings under my 600W hps, the light is about 18'' away. Temp is a constant 80 and I have them on a 20/4 light cycle.

They are 5 days old now, and I'm getting kinda worried about some stuff..

Some of the seedlings stems are like kinked or something right below the base of the soil, so I have to cover the bottom of the seedling with soil to make it stand straight.. Is this bad..?

Also, some of the small jagged looking leaves on the seedlings are dark green, and some are light green.. What is this?

Last, some of the seedlings leaves are drooping.. Why?

I'm confused and can't find any specific answers from google anymore please help! Thanks!

18" is about the minimum distance you should have full grown plants from a 600w bulb. Clones and seedlings should be about twice that distance away.

As long as the root tip is pointing down and is covered with soil, you should be fine. I like to keep the pod leaves/shell above the soil when planting seedlings and others plant the whole seedling underground. A little zig-zag in the top of the root is normal.

Probably wouldn't be able to say much about the leaf greenness without pics but some seedlings are hardier than others, getting greener faster.

Ok thanks, so it seems like I'm probly just worrying myself for nothing then

I have another question.. How often should I water? I have them in 2 gallon grow bags, I'm just watering the area around the seedling with a few splashes of bottled water whenever it feels dry about 2'' deep

Try not to overwater the seedings, I usually water them once a week for the first two weeks but it's all about when they need the water. Once the top 3/4" of the soil is dry, it's probably time to give them a water. I have a PH/Moistness reader that I got from my local gardening shop, they're pretty cheap and useful - perhaps buy one of those?

May be too much light too early. Pics?

With seedlings you want to let the soil around them (soil touching the root, not necessarily the whole pot) get almost dry but not quite. Make sure to only use seed starter soil or a similarly inert medium for seedlings, usually in small cups because they will need to be transplanted to fertile soil soon after. Even the worm castings and other amendments in regular good potting soil can kill the little ones. Using seed starter soil, the dirt under the surface will be just a shade darker than the bone-dry soil on top when it's ready for water. Ideally, the top half of the root will be in completely dry soil while the bottom half is in just slightly more moist dirt. Healthy seedlings will perk up and stretch out their roots when the soil completely dries out and this is usually a good way to encourage root growth. However, if there's any problem with the seedlings or if you want to be extra careful, don't let it dry out all the way.
