Ok so I just did a PH test and its around 6. What should it be around?? Also how often should I be watering?

These are the ferts that i have been using.
One is fish emultion stats are, N-9%, P(as water soluble)2%, K(as phosphate)6%. Havnt used this one is a while but recently been using,
Yates Thrive(Maximises plant health)stats are as follows, N27%, P5,5%, K9%, not sure if I should be using this seeing as the N level seems far too high.

I live in Australia so if there are any suggestions on what I should be using for fert thatd be greatly appreciated.

Please reply a.s.a.p please. :thumbsup:
