Well i,ve lost 10 & another 2 look really sick

My large(single growth) roth & supardi haven,t missed a beat .
Paph Berenice has 2 well formed buds.
I,ve lost 1 off my paph roth seedlings but the other 1 looks absolutely fine.
I,m absolutely gutted.
I can replace the lost 1,s quite easily but i,m not going to bother.
