Deficiency for 2 weeks HELP

Hi mate, looking at your diary its hard to believe the colour change in such a small amount of time. The first two pics show a healthy good looking plant. The last pics show a plant with heavy nutrient toxicity. Looks like you've used a filter on your camera. I would keep an eye on your PH as that is probably causing the brown spots. I would just feed her PH 6 water for the net couple of weeks so she can get herself right. From there take note of her progress and adjust your technique to suit. I hope this helps, good luck and happy growing

There was no nitrogen in any feed for these past 2 weeks and the clawed and dark leaves didn't show up until the spots started forming

Well first you had too much nitrogen in blooming. Is why leaves are dark green and clawed. Nitrogen in high amounts will hinder bud development.
