Thin Stems. (How to fix?)

My 4 babies are about 2 weeks into veg and i stretched them a little bit in the first week but has been corrected for about a week, the stocks are verry thin and flimsey, infact on 2 of them i had to insert a small straws around the stock to straightin them. and what i did insted of transplaning them i just toped of the pots with more soil it burried them about 2-3" from the first set of leaves.. i was just wondering if anyone has tips on how to thickin up the stock and make it more beafy . ALSO!! I would like to kno the differance between veg stage, and flowering stage, and when do you make the switch?

and one last thing, how long untill the seedlings show signs of gender? (male/female) and what are some signs? THANKS ...

Um Have you tried getting a fan for some breeze?Also difference between flower is the light cycle turns to 12 hours light and twelve hours dark,you can throw your plant into flowering anywhere from 6-8 inchs but with a longer veg you get a better harvest so its really up to you

Just put the fan on em... the movement of the plant will thicken the stems..
I gotta do that to a coupla my seedlings in thenext few days..

you can bend them slightly ever so softly with your fingers that will work too.. just dont be over zealous...

yea u definately need a fan. And while there in veg u can also spray the leaves with water to help the plant strengthen its stem.

????????????

??????????????

why even bother suggesting sprayin the leaves??

Just put a pc fan on em, theyll thicken up considerably in a day or 2.

i dont know i guess I thought I was able to share my opinion but I gess not.
