What's wrong with these?

They should've been transplanted a while ago. Like a loonnngggg time ago. They are severely stunted and I'm assuming root bound with multiple deficiencies. The second five finger leaf set should be the size of an adult mans hand. Trans plant them asap and knock off the dead leaves
 
grow bibles to the rescue
with limited info I can see two issues

you water to often, dont have proper atmosphere controls
 
Overwatering looks like it's cause most of these issues, washing away the news is one of the easiest ways to get deficiencies
 
Are they in the process of cloning or seedlings? not enough info. They look crap whatever stage they are at. The mother plant must have some issues.
