First of all thank you for a good site.
Now to my problem,(sorry for bad english)
My plant look very sick,thought it was overwatering so havent given it any water for 4 days.(that havent helped)
If i stick my finger deep in the soil i feel its not wet but not as dry as it is on top of soil.
Have been under hps for 14 days 18/6 ,and one week ago the edges of leaves started to curl.(look at picture)
This was a seed taken from what i smoked a while ago.
My setup is: 10 litres bucket with "flowersoil" and leca and sand,light is 250 watt hps about 9 inch from top of plant 28 celsius in closet.
No nutrients added yet ,(have biobizz).
Dont know what more to say,happy smoking from Norway and please help!
