S/H Phal seedlings - liquid fertiliser - how much?

[OzPhal]

Hey Everybody,

I'm new to S/H but to date am loving it! the root and leaf growth is just amazing, the vigour, colour and general appearance of the seedlings is amazing.

I have about 45 Phalaenopsis seedlings growing in 100% perlite with a light gravel covering. They're seedlings and i have seen new leaf and root growth. I just went out and purchased some liquid fertiliser it's made by "Growth Technology" here in Australia and is listed as containing the following:

Typical Analysis %w/v

Nitrogen 1.29
Phosphorous 0.31
Potassium 1.01
Calcium 1.00
Magnesium 0.40
Sulfate 0.15
Iron 0.031
Manganese 0.0095
Boron 0.0021
Zinc 0.0020
Copper 0.0010
Molybdenum 0.0005

Now firstly is that a pretty good mix? is there anything that i should supplement it with? secondly, how much should i apply? I have a reservoir that the pots sit in and that is permanently filled. Should i go with little continously and then flush every few weeks? or should i go with a dose, allow it to sit for a few days, then flush and fill with plain water? any thoughts/advice?

Kind regards
