The leaves get very thin and soon dry out like the other plants i showed in pics before. The 10-50-10 that i added 3 days ago doesnt seem to stop the sickness :S

Should i flush? PLEASE help me!!! As you can see there are some marvelous flowers that i might lose if i dont fix this problem...
Can this be an humidity problem?(i might have a broken humidity-meter)
N defficiency?
P defficiency?
Nute burn?
HELP!!!
