This is their 6th week from seed. They're in 80% ffof 20% coco coir. I heard that if you didn't wash your coco before you mixed it, you'd have salt build up.. I didn't wash.. 
I've semi flushed my plants two times since they've been growing. Anywhoo.. I switched over the 17th (two days ago). They go from 11am on to 11pm off. I switched from a 400w mh to a 400w hps. At 11am, they were good. I left, came back around 9pm and two of five of my plants were drooping with a few bottom leaves dying. I know it's not over or under watering. I water them at the same time and have only gotten a droopy plant when I flushed. I do the finger soil test and pick them up to gauge their weight. Even then, the droop is kind of different. The plant seems to condense like it's hugging itself when it drooped when I flushed. This time, it's more of the plant seems to be spreading out and just falling apart. Temps don't go pass 87f, humidity stays from 40-60. It only raises up to 60 when I water. I have two fans blowing on high all the time. I didn't fert before I switched. Today is my first time ferting. The only change I made before they started drooping was hps and 12/12. I've been trolling the forums and have seen a trend of this. As soon as someone switches to flowering, their plants droop. The weird thing is.. only two are doing it out of five. Any help?
