what is going on! please help!

I heard of dissapearing haze, apparently its a bitch to grow

I got twelve plants in the room the rest are fine.. no one picked anything off cuz I'm the only one who will go in the room and I didn't pick it off.. that's y I'm asking the question.. I got a pic of what it looked like but from last week to this week its a big difference . Even the guy from the hydro store dont know wtf it is.. the plant is four feet tall and all the bottom colas or colas half way up are perfect just the top ones are like that..

What a nightmare!

hahahahhhahahhahhhaahha. dissapearing buds!!! LMAO

Yeah, my buds dissapear too.
