if your gonna be growing id really change your picture and where you live. growers arnt the only people that read this forum. big brothers watching you, so take precations.

other than that i havnt had that problem before, the heat might be too much for them at the moment. this is my first gorw out side so dont have too much experiance out there but have been growing in doors for a little while.
after my seeds had germinated (indoors) id always use fluros for the fist 2 weeks un till they were strong enough to coap with hid's. so i gues it goes for the same out side. i'd assume that were you live the sun is like a hid and is pretty hot. so it might be good to keep your seedsling inside at a window or some thing for the fist 2/3 weeks untill they have hardened up.
didnt really have that probelm here in the uk, wish i did tho! cause more sun is better!! ubt i did start my seedlings indoors here, but that was many becasue it was too cold out side!

hope this helps, and i wish you all of the best luck with your first gro!!
