Calcium. Don't know why - there are several causes and therefore several remedies - but it's lacking calcium. Again, please start a diary.

Could be septoria. Hold it to the light and see if there's orange or a glow around the dots, could possibly be bugs.

White tips at the end. Brown patches. Leaves curling.
I've been feeding it 0.5L Advanced Nutrients Coco Big Buds.
The light was fairly close, at 30cm. I've raised the lights to 60cm.
It was also very humid, so I've opened the air vents .Leaves. Curl up
