my babies need help

[maxo-tt]

hello people, i just woke up and most of my seedlings are down.
i watered them 2-3 days ago, soil still moisten.
temperature 22 degrees celsius.
humidity 50%

i just got a fan off that night. maybe its ventilation issue?

it happened in just a few hours at night.

can i help them or they gonna die?

maybe water them again can help? or its worst in this case?

Re: my babies needs help

Your light is way to far away. See how long and stretched they are. That's what cause that. They will not hold them self's up that stretched out. Step one get a straw or something to put in soil to hold them up. Step two if you are using cfl out t5 t8 move light about 4" above them asap.

oh it looks like on the clear cups there is water on bottom. That's not good. Is you do not have hole on bottoms put 4-5 holes asap and wait until soil is dry before watering

Re: my babies needs help

maybe i overwater them?

i've added more soil. now they stand ok. but top side anyway down (

any idea what's that white spot on a leaf at a last pic above? its like a salt

light is ok, about 4"

p.s
in a previous year i had problem in flowering stage. all plants died with no reason. maybe some kind of virus(disease) stayed in my room? i save old pots with old soil in my room. may something like that happen?
those are old pics. they died at flowering stage last year (

one more question guys.

now i have 18/6 light cycle. maybe switch to 24hr ?

and maybe change them soil? or replant in a pure perlite few days to take fresh air? or just wait?

The plants look overwatered. Leave the light cycle at 18/6, dont stress those babies more.
