It seems I have a problem with the leaves slightly curling up on my Skunk No.1 plants. I originally thought it was due to the light being too close (600w HPS @ 21") but none of my other strains - HQS Skunk 3 X A2 and Aurora Indica are affected. It only affects the Skunk No.1 plants, could it be a genetic / soil problem ??? Here's the pic any advice welcome Cheers
They'll be fine...though try not to get water on the leaves like that...especially when using a powerful HPS...The droplets act like magnifying glass and WILL burn the leaves...
