Coco help please.

[Dankdad64]

I have a Hanna meter and I understand ppm. I'm having a hard time grasping ec and how to do it. This is my first coco grow. Canna coco and nutes. Any good videos or words of advice. I'm bad with math. Thanks for any help you can give.

Is canna coco 4ml of A plus 4ml of B ?
It's on the bottle. Along with some sort of recommendation regarding the EC that would produce. Something like 1.2 + tap = 1.5-1.6?

It's certainly on the bottle.

Thank you I will look.

Have you grown before the a ppm meter, and have a number in mind?
I can do a couple of conversions for you

Sometimes things come with instructions. It's the bit of folded up paper with foreign stuff on. EC instructions often contain a conversion chart, I'm told.

mS is EC

my meter uses the Hanna 500 scale
its easy to convert in my head if I think of 1.0ec as 10 and divide by 2 .... equals 5
or: 600 x 2 = 1200 .... 1.2ec
500ppm = 1.0ec


so add the 4ml to a gallon and see how many ppm
adjust as desired

Its better to go by ec and or ppm rather than how many ml but after awhile if you are feeding the same strength you will know how many milliliters equals what ppm on your meter

A good starting ec for plants in veg is 1.0 - 1.2ec
seedlings more like 0.6 - 0.8ec

My recent cheap ones have come in uS. Making an EC of 3.0 into 3000
It's easy enough to not see the dot anyway, so it looks about the same.
The extra digits offer a bit more resolution, but it's like using lab powder pans, to check keys of hash, still in plastic wrap. Quite ridiculous.

Thanks this should help.
