hi all let me say that i love sweetseeds never have any problems but i do in this run 

 

had 10 beans in coco for 15 days and for some reason the leafs are drying and curling on a few but not all

 

as pictured large.20181119_205701-600x800.jpglarge.20181119_205653-600x800.jpglarge.20181119_205716-600x800.jpg

 

 

my thinking is i have lights on 24/7 to keep it warm in there 25c to 28c  but done this un past no problem

 

ive moved light away there us 210w of t5 in there maybe bit much but been fine before 

 

 

possibly humidity??

 

any ideas ??

best wait for an expert, but to me it looks like heat/wind burn as if a fan had being blowing hot air on them directly. maybe give a few more details on the humidity and root temps or maybe light was to close. if ur feeding or not feeding?

yeah mate coco has nothing in it so u need to feed pretty quick, if ur germinating in coco you should really soak the coco in a light feed otherwise the seedling will only be able to feed itself at most for a week or two and then it will starve, so ya have to provide the feed from then on. As far as I know a seedling can only provide its own feed for roughly about 10 days unless theres nutrients in the medium. best of luck:rockon:
