looking at the pics i would say they look burnt which is light or feed problems...having read your info i dont think theirs anything wrong with the light.....so it must be feed.....if i was you i would boil the kettle wait for it to cool right down and water your plants no food....do this for a week or two and flush any feed away.after that start feeding with cool boiled water a bit at a time and maybe build the feed up
