Rainwater in coco

[zukinjo]

I am wondering if i use rainwater to dilute my fertelizer would it be a problem? I did not measure it yet. Have to buy PH and EC tester.

Maybe using Hesi Coco and the second choice is Canna Coco A+B...
Hesi as a more Simple solution.

Do they have enough minerals so i wont have deficiancy problems?

It’s been a while since I used coco, so much easier with the water only organic method. But anyway, I remember it basically stealing nutes so you have to keep ppm up in the water to stop it competing with the plant, you might need to add cal mag but the ratios are not often correct. If you spend more and get ‘buffered’ coco they pre mineral soak it which helps.
Much better to use proper soil, it’s a cleaner smoke, endlessly reusable and you don’t need all the bottles and test devices.

Use canna coco pro plus,doesnt need any mucking about,straight in the pot,dont have to wash it or anything.76

You do realize you are suggesting using soil in a coco thread?

Pure rainwater and canna Coco nutrients, and after outgassing to help stabile ph, will give you too low a ph.
I mix tapwater with rainwater in a proportion that after outgassing will produce a stable 5.8 to 6.2 ph.
With the plants I grow (low nutrient sativas) I do not have deficiency problems, nor do I add anything.
Peace

I don't know Hesi, but canna expects tap water. Your rain would need hardening up.
Is there something wrong with your tap?

I do not have tap in my location...

All the minerals needed come from your nutrients. Get something that you can adjust as needed like hakaphos basis (3 part) or kristalon brown (2 part).
