Seedling Question, NO emergency - any advice is appreciated

3 cheese ladies and 4 bagseeds have sprouted up nice and are all atleast 3 inches high doing well under some 150w CFL's for 24 hours a day.(is that too much light for 7 day old sedlings?) One, however has spouted quited tall and as its leaves grow bigger it seems to be a bit much for its tiny stem....My question is should i stake it or let it try and strengthen itself on its own? I have the lighting on the left side now to let it reach the opposite direction.... When should I intervene if i don't see improvement? here are some pics so u can see, thanks for any advice.

I think this whole 24 hour lighting thing is ridiculous. I don't see any upside to using it.
Plants need a dark period in order to function. Its basic Botany. At night they use the energy that they captured during they day-time photoperiod to perform different functions like thickening it's stem for example.
Slowly and I mean SLOWLY ween them off of 24/0
23/1
22/2
21/3
20/4
19/5
stop at 18/6 until flowering.
If you jump photo-period down to 18/6 right away it will stretch.

happy growing

thanks yeah i got em on 18/6 now they are doin good i've had troubles with a few things so far but other than that good, thanks for advice will post more pics soon their growin fast now under this 400w MH

Ed Rosenthal seems to disagree, cannabis does not need a dark period in the veg stage.

You can give them 24hrs of light but I do 18/6 I like to give them a break plus the lights been off you can give a bit extra foliar feed my girls love it when in veg.

Tie your tall seedling loosely! to a stake she'l soon hold her own keep fans on as per.

only use one large hps light can't help you on last one. GOOD LUCK growing
