When you first switch to flower you can top dress with the high phosphorus Guano, along with the kelp and some worm castings. Do it again every few weeks. But once you're like three weeks from cut down I would just plain water and don't worry about adding anything else.
Now as far as your other ingredients. You don't really need the lime or the perlite yet...but you can use them eventually. Same goes for the blood meal, most organic growers will tell you to avoid blood meal, but hey you bought it so I'll give you a guide for utilizing it.
You can make use of the lime slowly over time. After you harvest, before you reamend and reuse your soil...get one of those cheap soil pH testers at the hardware store. It probably will be fine the first couple times but as it lowers from the peat breaking down over time adding the lime will bring it back up.
Now when it comes to reamending your soil, that's when you can throw in the blood meal. When you reamend the soil for reuse, use the listed amendment recipe for your original soil above, same ratios, but add blood meal to the mix and mix in some of the perlite you bought to make sure it stays nice and aerated. The clay pebbles can probably help serve the same purpose.
When it comes to the Epsom Salts, maybe run yourself a nice hot bath after all that soil mixing and throw in a couple cups and soak your wore out muscles for a bit! Lol...also if you notice any magnesium deficiency during your grow just throw in a tbsp per gallon of em when you water and it'll clear right up. Don't do another feeding of it unless the deficiency returns. Holler if you got any questions man!
