Tough call but I think the TMV is pretty rare but I agree it looks similar. The dry green side looks like N toxicity and the other side looks like Cal/Mag deficiency and there is a chance one it locking the other out. I would forget the reason and jump straight to the cure, flush and then a root drench with some Recharge of similar and then start to introduce nutrients at 1/4 strength and watch for healthy new growth.  Keep us posted
