Hello all my o g friends I am new to coco after running d w c For many years had to change due to a nasty outbreak of algae I could Not get under control.
So this is my set up.
1 block 650 g core.
1 block 650 g Coco chip.
~20% Perlight
I believe the first mistake Was buying cheap coco.
I didn’t necessarily understand Preloading coco with extremely high levels of calmag before planting.
I am mixing nutrients using the ironhead formula.
At first mixing to an extremely high level of ppm I have since backed off
To PPM of 600 & PH of 5.8. I am using tap water with a starting PPM of ~250
I seem to be finding conflicting evidence online about measuring run off.
My PH has steadily drifted upwards in runoff to 6.5
But I have been able to bring my p p m down to 600 in run off. Yet PH is still 6.5 in run off.
plants have started rebounding from what I believe was a Calcium magnesium deficiency. And nutrient burn. Yet a few of them still look lime green. And others with what I believe is still a bit of Calcium magnesium efficiency.
So I guess what I am asking is the ph. Run off important and if so, how do I lower ph to the correct runoff level of 5.8?
If this is already been posted somewhere else, please redirect me. Thanks for all your help.
It is much appreciated.
