    Hi everyone,

    Please, I need some help. I just started a new job as a greenhouse technician and need some help in finding out whats troubling those roses! The pedals curl to the inside and in some cases its quite severe, its not a straight edge as in normal roses, it sort of roles inwards and looks ugly. I can not find and pest! So maybe a nutrient problem, the pH is around 5 of the run off water, which is to low, just working on correcting this. Could that problem be connected?

    Thanks for the help
