Some of the leaves are getting brown from the base/ center of the leaves out.

Others are having necrotic spots spread on the leaves, they appear at random places on the leaf, thought usually from the edje towards the center. First theres a green dead spot, then becomes brown and turns to a crisp, after that the spot just gets bigger via the principle.
And then i also have those leaves that just turn a light yellow/green colour and fall off.

Could it be from too much heat? I have radiators working in there BUT the damage started before they were put into use. Soil is slightly moist to moist. I recently sprayed with fungicide and pesticide, but that was also after tha occurrence of the problem.
Last year i didnt had such a problem on it, rhought the greenhouse stayed alot cooler.
Forgot to add the overall pic off the tree, doesnt look so bad...
