Calmag - hardwater area with 0.6ec

Post by wutang »

Hey all

I've been reading about calmag as I'm switching to coco but read contradictory stuff..the internet can be mind boggling!

So I'm in a hard water area and my ec is 0.6 straight out the tap. Do I need calmag or not?

Cheers
Wu!

Canna A+B is full of cal and mag already... If you think you need some, just up the ferts.

My water doesn;t even make the EC wand flash, I don't need calmag. My old house was 0.7-0.8 out the tap... I didn't need calmag then either.

I add calmag once every 3 weeks for 1 feed only as a precaution and never have any issues. My tap water is same as yours :)

Ignore this reading cus calcium in hardwater is more or less unusable by plant, basically its calcium carbonate in your water and way too big to be taken up through roots.

As to whether you use calmag or not well its your shout but if you buy a sack of canna pro plus its already treated and buffered with calcium that is usable.

Bloody crazy how such a short distance water differs, mine is around 0.2/0.3 max and i dont really use calmag unless im using old coco and re buffering it with the stuff

As long as you're using a fertiliser that has been formulated for coco then you won't need it. Even with RO water I only need a small amount to buffer when using coco.

Hey @seymore_budz long time!

Hope you're good?

Yeah I went for canna coco pro plus, and their a and b after having a chat with Keeno. Otherwise I'd be a rabbit in headlights with everything the grow shop throws at me. Gr420 is love man.

I have some pk13 from a few years back..bottle is mostly full...and thats it. First time in autopots so lots of new factors to consider this time so just want to keep everything as simple as possible. Already killed two seats in overwatered peats so I've gone old school with germinating in paper towels..always worked before. Then ill make sure my jiffy peats arent too soggy and drain them like mad before the seeds go in there. And then into coco which is going to be all new!

Do I need to do anything with the coco and clay pebbles before I put them in pots?

Cheers!
Wu

Yea man long time no speak dude! Overwatering is always a concern when germinating mate I've been growing a long time and still kill seeds from time to time by overwatering. I find the peat dries out real quick too so I always end up over compensating and the don't like it.

I agree with Paul mate just bang em straight in the coco. Coco and peat have very similar qualities so they will thrive in just coco if the conditions are right.

I always rinse my pebbles. Some say it's a but pedantic but I always find washing them put my mind at ease.
