Ok I'll try to help as much as I can with info.
Two girls: Tegan and Sara from cheap mexican schwag bagseeds
Hydro, ebb/flow, 15 min flood every 2 hrs, aqua A&B, NPK 0-13-14 flowering
1000W HPS cool tube, 6" planters with hydroton clay pellets

They will finish their third week of flowering tomorrow. Tegan has always been well and robust, but Sara looks like she is definitely hurting. Her flowers and most of her leaves have a very distinctive curling at the ends, the tips are brittle and break under pressure. Lower leaves look very bleached/yellow-green compared to Tegans very dark green.

Tegans topmost part is 19" from the glass of the tube, Sara is 17".

There have been no critical issues, pests, bad nutrients, missed feedings, miscalculated nutrients, or environmental stress. Tegan is doing just fine, and Sara is going crazy.

What really worries me now is that one individual flower on Tegan is starting to display a curling at the very ends of its leaves akin to Sara. I don't want Tegan to start hurting too.

Here's an album that should help, all the shots have descriptions so you know what you're looking at. If it asks for a guest PW, its Greenie with a capital G. Take care and thanks!
