apparently its loaded with pk and it needs removing?
This is where i use it to my advantage as an organic ammendment. I just add calmag and N and it can grow a houseplant for a while before changing mixes.
So to people who want to start "clean" then yes , it would need removed. K im sure coco has a lot. P im not so sure.

You said you flood in trays im wondering if your running e&f or only for your babies? I always top/drip feed with coco.
I used to grow in fabric pots with coco, and always top fed them. Then I switched to rockwool slabs and started flooding them. Then I switched to coco cubes to mimic the rockwool.

I use Canna Coco Professional. Although prebuffered I rinse a low nutrient solution through it. Around 300ppm-400ppm. This cleans the fines out and I can ensure that it's fully buffered and at the ppm I want it. My last grow I did a plant without perlite. It grew just as well as the perlite mixed coco plant if not better. I won't use perlite again. It's just not needed.
I stopped using perlite years ago. It's not needed and I hate the stuff. I've banned it from my property. Some slips through in bagged potting soil but I'll never add it to coco again.

I also never use calmag either. Any decent nutrient should have enough which is why these coco specific nutrients are such a scam. It's coco specific but you still need to add calmag? It doesn't make sense.
 
Why fuck with a healthy plant?

Gotta stick with what we are comfortable with. Personally I feel the whole point of hydro is pushing the plant to the limt for speed and yield. If your interested in health living soil is a intriging path to follow. But i feel that salt based growing. Nothings ever going to be perfect every strains different. Requires different stuff. Theres to many variable to really get tied up on this or that. I prefer to push my plants in coco to get the most i can from the explosive growth you can harness in hydro if you are careful and methodic about your increases. Thats just me.

Coco is not ideal for flooding. Because of the cec your going to get imbalance as they use minerals at different rates.
That's the conclusion that I was coming to. A lot of people bottom feed coco and it's recommended in a lot of gnat threads, but from my experience it prefers "out with the old, in with the new."

I always push my canna coco through a garden sieve because ive found hard pieces and clumps

I've never pre-soaked it in anything, just used as is

What nutrient line do you use?

Canna coco straight from the bag. Botanicare rehydrated with a weak nutrient solution. Both of those brands are ready to go. Double washed, steamed, and pre-buffered. If people want to take the unnecessary step of rewashing what's already been washed then that's their call and their time.
Perlite is not needed. 100% coco. Plug in some blumats and you're on autopilot. Makes for a boring grow but It's so simple even a caveman can do it.

What nutrient line do you use?
I just use some dry nutrients similar to Jacks. The calcium nitrate I use as the primary nitrogen source provides all the calcium needed even with coco. Over ten years growing in coco and I've never once added additional calmag. I never used it with flood and drain hydro either. Never have any deficiencies.
