28 days in flower burned to a crisp in 24 hours

This plant was 100% healthy less than 24 hours ago. I did 2 things yesterday to my plants that was different than normal. 1. new bloom nute 2. moved the plants around to new spots in the cabinet I think maybe it is light burn? I have an aircooled 400 watt hps on them. The glass on the reflector gets to 82 degrees. They were about 6" away. there is plenty of airflow in the cab. If it was nute burn wouldnt it start at the bottom of the plant and not move as fast to kill the plant? 6 plants of 12 are effected and 2 of them I had to cut because the damage was so bad all of the sunleaves were toast. I gave them a serious flushing this morning just in case it was the nutes. help

was it fox farms bloom nutes?

It was a urea free 11-35-15 orchid bloom booster given at 1/4 strengh

Does it look like fert burn?

wow...thats an additive...your supposed to add it to the flowering nute...

Crap I flushed about a gallon of water through each of them. 6 of the plants are showing no signs of burning and see perfectly happy. This sucks I made it through this whole grow so far with no nute burn. Boo

Dats, welll start smoking....that's a tough one to swallow..you have learned a valuable lesson..don't fuck with it if it ain't broke..master your techniques that you use and everything will fall into place...just stay with what you know..good luck bro

I shouldnt have fucked with them they were 100% happy and thriving. Live and learn. I dont see how it burned them the fert was formulated by orchid specialists and endorsed by the american orchid society. lol
