relax my friend, even if they die, that won't stop you, you're a grower now
and all growers suffer losses, especially when they are new growers.

now, in trying to save what you have, don't transplant as that will just add
more stress, instead you need to flush them thoroughly.

what that means is to run lots of water through the plant to wash out those
nutes you fed them with. so, if they're in 16oz cups, run 32oz through the
cups, just let it run out the bottom.

then all you can do is wait a couple of days to see if they recover, and you
should see signs of improvement within a day.

if they die, it wasn't a failure unless you give up. if you keep at it then this
loss is a learning experience leading you closer to the day when you will be
self-sufficient.

personally, i popped 30 seeds on my first attempt and i managed to kill them
all. my second attempt i popped 30 more and only managed to keep 5 alive
through harvest. now, when i pop seeds, they almost always all survive. for
example, last year i popped 5 White Rhino and 5 Pure Power Plant seeds (Feb
i think) and all are still alive and providing me with cuts to feed my SOG. (i
got 5 WR females and 4 PPP females so quite a good ratio)

the main thing for you to remember is to relax and start reading the FAQs and
all the sticky's and just read read read, lol.

another thing to remember is that, until your plants have at least 5 or 6 sets
of leaves they are infants and so you shouldn't feed them anything at all.
also, once you do start feeding, always start by using 1\4 dosage to see how
the plants react before increasing the dosage to half.

and really, just relax, if they die you've only lost a few weeks time and you've
learned a lot in that time so it wasn't a waste.

i should have mentioned to ph the water myself, thanks to the other poster.

also, this is the exact reason i always suggest that new growers start with
bagseed rather than buying expensive seeds.
