thanks for all the tips!
I agree with the root rot theory,
right now it is getting worse only the preliminary two small leafs left green and all the others died.
i decided not to cover it with bag because it is inside terrarium, an humidity is fine!
so i dried the soil as much as i can and hope for good!
i thought that it is fungus attack from the leafs,but now i can see that it is coming from the roots. maybe it is fungus attack on the roots.
i guess that i don't have luck with N. fusca
,
last summer i boiled/cooked in the hot Israeli summer 100 fresh grown seedlings of N.fusca because i forgot to make holes in the covering nylon!
