Good day. I'm new to this group and need some guidance with my growing. I'm currently busy with my second grow. UK cheese. We just went into spring so night time temps take a dip. Anyway I transplanted them 2 weeks ago from organic soil to a coco/perlite grow medium. I also started feeding with General hydroponics flora series. Since transplanting some of the new leaves are taking on a silvery white sheen. Is this a concern and if so how do I fix? Posting pics....thanks guys!
