The answer you got in week 7 might be not completly wrong, but the spots on the leafes look more like a start of a thripse (or similar leafsucker) population. That does not look like a calcium deficiency to me. The black dots beside the spots is what they leave after dinner. If you have a microscope to check your trichomes, you can take a leafe with spots and check for yellow/green "worms" on the leafes (sometimes under the leaves).

Your diary suggests that you overwatered your plant through the whole grow. The soil looks always wet and I have seen weeks with 0.5 liters a day, what would be way too much for a plant this size. A plant that needs 0.5 liters a day should be 100 times as big. If the soil around the roots is not drying from time to time, the roots get no more oxygen. If you have started your seeds in direct sunlight that might have been a bit of a lightshock.

As always thanks to everyone for participation! It was tough to choose the winners as always. :muscle:
