Stem Problems Reall Bad!!!!!!!!!!!!!!!!!

well its about 3rd or 4 week into them they my babies are doing good but like in a week or so thye wont stand up right i have no idea why. Like the stem right were it comes up is skinnier and weaker a lil brown i think and the babies wont stand up straigh its happening to ALL 13 of them i have no idea why please help me!!!!!!!!!!!!!!!! theres a pic i mean you cant really tell but it does not look good. please help

i really hope is not pythium or damping off bc i see a some grreen fungus on my rockwool medium

please helppppp and tell me how to fix this

do you have a fan blowing on the tops of the plants?

ya i have an osciallating fan blowing on them on low and i jus lowerd my 1000 watt a little bc the light maybe to far away. one actully jus now died with in 5 minutes it fell over i put it up and i went back in and the leaves were like drooping straight down it was horrible, ya i hope its not a fungus problem bc its on majority of them

must be man. if you have a fan moving the stems they should of built sturdier stems. maybe its something that is breaking down the cell walls inside the stem and the plant doesnt have the rigidness that it would of if the cell walls were 100%. thats my biology guess lol

ya i think it is bc the stem is pretty dam thick jus right where the line starts its thick then right when it goes under it gettts a little thinner so im gonna get some fungicide tommrow hopefully that will do the trick hopefully. im gonna be pissed if more die soon haha well if any one else has a educated guess please help ahaha well now i gotta go releive stree with some

peace

it wouldnt be a bad idea to cover those roots up either

I have been having trouble with weak stems too....I really don't know what the long term solution is, but you have to support them, otherwise their stems may get fucked up....which is REAL BAD. So, your going to have to help them up until they can get stood up on their own. You get can get supports from any gardening store. Don't totally support them, otherwise they won't have any stress to build up the lining of the cell walls. Good luck....

fo sho ya i cut styrofoam cup in half then up the middle so its supporting it.
also i see theres fungus on the top of my rockwool probley because i top feeded for 2 weeks by pouring water and nutrients on it, so since fungi needs air light to survive i put mylar on my rockwool and put a split in it so it slides perfectly thru the stem, hopefully this will help till iget the anti fungi spray or what ever at the grow store.

Put A Fan On Them
