Newbie help please: outdoor grow with Coco Coir

[chucker8]

A few months back a friend gave me a few seedlings that were in small plastic cups. I began researching on how to take care of them. I learned a lot from youtube, so I created my a new medium to transplant the seedlings to - coco coir and perlite. I buffered the coco using Cal-mag and began feeding the Coco Canna A and B products.
Being new to all of this I later learned that the coco medium and liquid nutrients are more designed for hydro/indoor growing ?
I am strictly outdoor planting.

So for a few weeks I fed the liquid nutrients to the plants in the back yard (in 3 gallon containers). Just a few days ago I transplanted into new 5 gallon containers using a mix of 33% coco, 33% perlite, and 33% horse manure (aged).

My question is, do I still continue to feed the liquid nutrients? Or should I stop because there's now manure in there. Also, I read the rainwater is bad for coco plants since it will flush out the nutrients. Is this still the case?

Thanks for any advice/feedback!

Hiya chucker, plants are looking nice and healthy.
The manure should help feed the plant depending on how much you put in there and how strong it is. If the plant starts to yellow at the bottom, then use your liquid nutrients again.

I'd rather use rain water than tap water, but my tap water isn't brilliant.
Just one thing, putting organic matter (manure) means you have to raise the ph slightly to compensate, about 6.4.
