i agree with rusty...ower water and i had a similar thing happen but with bud blood...i mixed a liter but added what normally goes in 4 liters and it literally cooked the plant very similar to what your first photo looked like...so it may be a over dose of pottasium...with open sesame rated at 5-45-19 and feeding every other day that is my best guess here...if those white spots are not caused by mites
