Hi Chilly ^_^
Do you have a PH meter?
Ideally you will want to check your feed PH before it goes in, and see what the PH is of the run off - then you can calculate the Soil (or medium) PH using this formula.

Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference
If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.
For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5
If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

1.5cl per 3 litres works out at 5ml per litre which at this stage seems about right. Keep an eye on your leaves, if they are yellowing (presuming you have your soil PH in the right range), then you need to up the feed, if you see the tips burn and turn yellow/brown, you should dial back the feed a bit.
PK 13/14 - I've used it on one grow and thought it helped. I;ve bought some more, but my good AFN buddy Mr Jorilla Ganjamoto has suggested that i might want to flush it down the toilet (lol). He is a big fan of Dutch Pro Explode as an alternative and judging by his results, It is very difficult to argue ^_^
