I have read almost every article I could find on leave curling, but couldn't find out why my leaves are curling up. (1st picture)
Also there's some spots on one of the first leaves at the bottom and I have no idea why they are there. (2nd picture)
I put my thermometer in 3 different places and the temperatures are between 23.5c and 26c.
Humidity is between 30% and 35%. (I know this isn't good but I read that as long as it doesn't drop below 20% it should be fine)
My 250w MH is hanging 60cm above the plant.
