I should have mentioned that I have a plant that is doing that (indoor grow) but it's at 12 weeks and likely at the very end of it's cycle so I am just watering with plain PH'd water for now. It otherwise seems healthy so I'm not doing much about it.

Man those are beautiful, except the pale one, are you growing outdoors?
Soil or coco? What you been feeding them?
