what is going on with my babies??

[greenmonster]

hello all,
im stuck as to what is causing some of my babies to wilt up and die. can anyone help me please?
all of my plants have the same routine, same soil, same temps, same amount of water and nutes, same distance from light etc etc so i cant work out why some are healthy yet some are v v ill.
these plants are 'Early Girl' and from seed which i bought from sensi seeds. They are in the same brand of soil that i have had no problems with in the past and are undergoing the same routines as my last few sucsessful grows yet some of these are just dying.
They are veged under about 180 watts of blue light and i try to keep the temp around the 25C mark yet this has proved difficult at times lately as the temp outside has been 30+ at times.
I had'n't fed them any nutes till the other day where i gave them a small dose of baby bio yet these symptons were showing before i gave them nutes and it seems to make no difference. Today i watered tham again with a slighty higher doseage of B bio (like superthrive a bit) and also gave them a small dose of epson salts.
im pretty sure i havent overwatered them and they certainly havent been underwatered. Even though u can see on the pic that the yellowing plants are drooping, this only came on fully yesterday and that was 72 hours from last water so i count out overwatering ( i think) yet when i watered them earlier they did not perk up as plants do when they are suffering from lack of water and get some so i dont think it is this either.
oh yeah my PH is roughly 6.8 and i have 2 fans blowing on them for good air flow, cant think of any more environmental facts to state just now...
ummm does anyone know what is causing this?
thanks for your time
monster!
oh yeah the first photo is a healthy plant and the rest are of 2 of the unhealthy ones.

how big are they?what size pots are they in?

[mscaboo]

they look like they need some n,what is the n-p-k of the nutes you are feeding.i am not familiar with baby bio

[greenmonster]

the plants are 2-3 inches tall, and in pots roughly 4 inches deep and 4 across the top. N-P-K of Bbio is 10-4-2. i wasnt going to feed them just yet but this problem forced my hand a bit.

i would keep feeding nutes.just remember the leaves that are yellow will not turn green.i think you ran into a n def.did you add dolomite lime to your soil?i highly recommend the lime

they are not happy with something r they? i think they need a flush with pH adjusted water about pH6. then water with a full supply of macro nuts. and micro nutes. hope that helps you. skunkymoo:stoned:

baaa they have got so much worse overnight that ive given up on them. I just threw them out of the window onto the street this morning: wooooops. extreme anger may have just got me busted lol. but they are so shrivveled and ill looking that hopefully noone can tell what they are.
bugger it, should learn to control my anger,lol

thanks for your help guys

They look overwatered to me. And N deficient. But with overwatering you can get weird def symptoms b/c the plant can't use what you give it.
