what percentage of perlite and lime should I add?
Don't add lime!!! Please trust me on this one. Lime "buffs" your pH, which basically means that it sets it to 7.0, exactly 7.0. The science behind it is extremely complex, but basically the lime (Calcium) has the capacity to absorb all H+ ions within the soil, without adversely effecting the H- ions. The end result is a stable pH of 7.0. This can be a vegetable gardener's best friend, but also can be a cannabis grower's worst nightmare!!!
Please research the importance of the pH of your soil. Fox Farms has the equipment to properly set their pH levels, you don't need to be Bill Nye the Science Guy at home and think you are going to improve it. That's why they apply science to the process of making it. Phosphorous, arguably the most important nutrient considering roots can't grow without it, can only be partially uptaken by the cannabis plant at pH levels of 7.0. This will result in nutrient lockout that you will probably mistake for nutrient burn, it is one of the most common mistakes people make, and misdiagnose when starting to grow herb.
To answer your question....I think Happy Frog alone is perfect for cannabis. It needs a little peat moss added once you mix up your flowering mix (It should be a lower pH, around 6.2). But from seedling to week 1 of flowering, I use straight up Happy Frog. Ocean Forest is too heavy on the nutrients, and the nutrients in it are also slow to breakdown, which can be a good or bad thing depending on who you ask.
