seedlings at 1 week old.

these are my plants at 1 week old. 2 of the 3 i have are way ahead of the other one since seed. what could this be due to? do my plants look healthy? theyre under 2 20w hps. also the first set of leaves on some have got yellow edges. is this ok? thanks for the help in advance

look fine to me.

the first petals, the ones that turned yellow, they fall off anyway, so it shouldn't matter. if you have yellowing on more of your leaves, then you would have something to be concerned about.

looks like you're soaking the soil.. don't soak it... use a spray bottle instead of pouring water into it

Yeah, you might be over-watering a bit... Water only when the pot feels light when you lift it, if there's too much water the roots can't develop properly.

should be overwatering happend to me before the petals start to get yellow if you keep overwatering then the leafs are gonna start to get yellow also

i have been spraying them. i had just watered them that is y they are wet. could there be any reason why one is smaller than the rest?

You are watering too heavily for such a small plant. As suggested, use a spray bottle to water with, or a syringe with a small amount of water..
