Mixed Selection outdoor grow

I had a bit of a scare the other morning when i had to go too the doctors and i was in a rush and didnt manage too water my pots the day after planting them before they had sprouted. It was a very hot day and as i got back i went out and found all of the pots soil completely dry on top. I managed too get them watered and the following day 6 out of 8 have sprouted. I am hoping the last 2 sprout over night. I am very surprised the baby sprouts under the dry soil had survived as i assumed they were all dead. Well i dug a bit around the remaining seedlings which hadnt sprouted and i managed too find them but one has very yellow leaves and i hope it will survive. I think it needs some light so hopefully tommorow should fix it, I also uncovered it from the soil so it doesnt have to try too hard too get out. The other one however did not go well as i couldnt find it for ages and then i found a white stalk poking up with no head on it just a stalk. I did find the seed which was a bit deeper next too it and it seemed pretty tight together, so i tried too open it up but i didnt find anything inside. I may have knocked the head off while poking around trying too find it with a chop stick.. I couldnt resist playing about with it but i am near enough sure it was a goner. I carried digging and i found what looks like another part of a stalk with green leaves around the top but it was shriveled up quiet badly, this was a bit away from the other stem i found. I am not sure if it is just an ordinary weed or not but i have put its stem under some soil and left the head poking out and i will see what happens.. It may have turned around in the hole and came up the wrong way, i am not sure exactly what happened here. I was being very careful when i planted them but it may have dried up when i left them without water. I am a bit sad that it was one of the blue auto mazar's as they are supposedly one of the best auto's on the market and are heavy yielders. The other yellow seedling was also one of the blue mazar's, they looked really healthy after germination but seemed too have the worst start of all of the seeds. I think it was my error though. Could be a few possibilities as too what caused this. But overall i think 7 out of 8 should be ok. We shall soon found out..
