As far as the plants you are trying to save, a good trim up job I would also say is needed. Now that they are damaged you should really reduce the size of them, it will help the chances of the plant recovering. I would be only foliar feeding them with water, and some liquid Karma. I would also lower the ppm, to half what you were @ to help them retake. From the look of the photo, you might want to get some new clones going, or new seed stock asap. If you had a mother I would say to ice these bitches and start over with the help of the people on the forum. If you take pics we can really see what is going on and help you.
oh yea, and I like you shoes and all but you should never put your dirty ass feet in your table. That is a good way to contaminate shit. Cleaner is better, a mat a t your door with some bleach in it will also keep out pests that come in on those cool ass "sneakers"
