Early problem with seedling

Thread starter #1
Hello everyone this is my first time writing here but i have read lots of stuff here trying to educate myself.
Finally i felt ready to start my own little project.
My setup is a small tent with an 120w led panel i am using pc fans for ventilation 1 intake 1 exhaust and 1 for air circulation in tent. Temps are bettwen 22-28 celcius (72-82 F) humidity 40-60 plant distance from panel around 60cm or 2 foot. I am using biobizz light mix soil with perlite and cocofider in it.
i am using tap water leting it sit more than 24 hour to evaporate clorine and i have used only root stimulant (root juice biobizz ) 1 time only at 1ml/L
I am on day 7 now and first problem kick in.


strain is blue mystic from royal queen seeds. As u can seed tip of leaves start curling and i can't figure why cause temps and humidity are close to optimal.Also new set of leaves seems to start curling too.
Any help would be much apreciated.
 
i would supplement cal/mag when using Led . take a look at antics Led grow as he was experiencing issues under his Led and there are some people with allot of wisdom on his journal and a few more !

Few things.

Cal/mag DEF are more common in LED grows. I'm not sure why but its something I learned from KJC, you need to add more calmag when using led lights.
That being said, that plant is too early to have a def as should of had enough food stored up within itself.
To me it actually looks like wind burn, do you have a powerful fan pointed at them?
