someone please help before she dies (pics)

i already lost 1 and i have 2 left... please tell me whats wrong with this plant before it dies too.. i dont know whats happening their dying young... & i dont think its overwatering..

the temp is a bit high but i cant get it under 80 even with ventilation and a fan.. in daytime its 90 and at night its 85 and when i put the lights out its 80... but i just started using co2 by the yeast/sugar/water method because i heard that the plants can stand more heat with co2..

it has been a week now and the leaves started to curl upwards and turn light brown and dry out.. i decreased the lighting to just 1 CFL (36W 6500K) instead of 3.. because i thought its burning from heat but its getting much worse now..

i also transplanted it to another pot with perlite with the soil to improve the drainage..
Im beginning to lose hope in growing.. i really want this 1 to live so PLEASE HELP

Yep those temps are a bit high. Are you giving any nutes or just plain water?

this is how she looked about a week ago before she got sick...

just plain water.. but the soil has nutes in it

try using some soil without nutes next time or some seed starter mix it looks bad try to get temps down

sensitive stuff

Bummer! What kind of light are you using. If its HID make sure plants are far enough away and let your soil dry before you water again. Looks overwatered to me. Roots start to rot if kept too wet. Very easy to do! I would water with a shock treatment next round but let dry first. Wait till pots feel light when you pick them up. Good Luck!

they're getting worse

i would if i was you get some new growing medium. make sure you buys stuff WITHOUT nuetriants in. these burn seedlings and that is what looks like is happening too your seedlings.

Temperatures especially at that early stage of life is detrimental to the seedling. Ideal temperatures with co2 enrichment would be around 85.

so the problem is the nutes in the soil? i didnt know that it would kill the plants .. thanx everyone.. but i think its too late for me to fix the problem..
ill start again from the beginning..

no

give your soil a real good flushing if possible, then keep going, maryjane is a strong thing and can normaly come back, so i would keep going and learn from your mistakes. things go pete tong in everyones grow and you learn from that mistake.

do not flush soil with time released nutrients in it EVER it will release way too many nutrients and burn the hell out of the plant and kill it dead.
i would suggest you get it into a soil with no nutes in it and use water only until the plant is atleast 3 weeks old
