Seedling looks a little sick

Hi guys,

My seedling is probably about 8 days old now, it started quick and grew its first set of leaves in the first day or two, then stalled for about 6 days and appeared to do nothing. I assume it has been growing roots as i can see little roots sneaking out the bottom of the pot. It has been a nice healthy green colour the whole time and it appeared to finally be growing a second set of leaves yesterday, however when i got up this morning i noticed that the leaves have some brown looking patches on them. The soil is a mixture of organic potting soil and perlite and it has been watered around every 3 days. It is under 4 23watt cfls, 2 blue and 2 red, and 1 blue 48 watt cfl, the lights are about 6 inches away from the plant. Temps where a bit high until yesterday (around 85) i have got it down to about 80 now with some improved ventilation. I have no idea what the humidity is.

My little point and shoot camera has a lot of problems taking close up pictures but i think i managed to get some decent ones, any advice would be greatly appreciated

Here is another picture of what it looks like today, the brown area has not really increased in size just become a much darker shade of brown so it is more visible, the new set of leaves still appear to be growing slowly. I am wondering if this seedling will make a recovery or not, i am only growing a single plant (feminised seed) and i am wondering if it would be best to start a second one and replace this little guy.

If i do start a new seed i would love to have this guy diagnosed so i can figure out what went wrong (so i dont repeat it), i figure it was most likely drying out due to the high temperatures, (reaching up to 90+) in the original chamber, it now never reaches more than about 82.

Thanks guys.

Well she is still alive and growing. The new leaves are still every so slowly growing. Its a bit hard to tell but the leaves have drooped down a fair bit since the previous two pictures.

Im still unsure what caused this and if the seedling is likely to survive, i am considering starting a second plant but i only have 2 seeds so i dont want the same thing to happen again. So if anyone has any ideas as to what happened to it they would be greatly appreciated.

Well i think she might be dead, the new leaves are still growing but as you can see its 5 days from the first post and they are still tiny, meanwhile the rest of the plant looks to have died off.

I have started a new seed germinating today and have changed the potting soil to a new mix the old one had something called dynamic lifter in it. I have also lowered the ph of my water a bit, before it appeared to be about 7 maybe a little higher, now its at about 6.5.

I will also keep it a bit further away from the lights and about 5 degrees cooler than the previous seedling. Hopefully all of this will prevent the samething from happening again. If anyone has any comments on my idea, or why the old one died i would love to hear from you

I will keep the current seedling growing and maybe it will recover.

Thanks

she looks on her way out

i felt your pain.

my plants did something of the same thing.



this looks like either heat damage or nutrient solution burn.
are you watering it frequently

the nutes in the dirt good be burning your gal to death.
try to not water her for a day or two.

or if there is light close to her take it off a bit

I would guess your problem was a combination of letting the temps get to high, and probably nutes in the soil. the seedlings don't need any nutes at all for at least 2 or 3 weeks. It could definitly cause them to burn like that. Run a small fan across the tops. It will help keep them a little cooler, and will strenthen the stems. You should be able to set your floras a couple inches from the tops of the seedlings without burning them, otherwise they will start streching. Keep water off the leafs. It causes a magnifing effect that will burn the leafs.
