Any idea on sick leaves?

I'm about to start week 6 of flower. My best guess is light burn, (250W HPS about 14 inches from canopy), but I could be wrong. I've switched to my LED light to help. Any advice or ideas would be much appreciated. I've been very conservative with nutrients, using 1/2 str of the FF lineup once a week.

It's normal that the leaves start yellowing the last weeks of flowering. Those brown "dots" however - that looks like a cal mag deficiency. Not 100% sure though. It can possibly be other causes
 
Looks pretty healthy bud I wouldn't be too worried.. my LED (and HPS sorta..) girls all need a good kick off CalMg around wk5-6. For the gallon I'd use around 5ml. (1.25ml /L). It's hard to overdo the CalMg
