I have also used PK13/14. But the schedules I use are different to the one posted above. For a 9 week flowering strain you add PK13/14 at weeks 5,6 and 7. Week 3 seems a bit early in my opinion. I grow in coco but here's a link to a soil version of the feeding chart I use.

Cannazyme stimulates root growth and also breaks down old roots.

Probabaly best to leave the molasses alone for your 1st grow. If you use the wrong type or too much it can damage your plants, it's kind of a cheap food supplement. If you do use it use 1 teaspoon of unsulphured molasses per gallon of water, no more than once a week.
