help plz...

I know you said those nutes are ph indifferent... but you have potassium def and look at the chart....

I'd say that ph needs correction.... IMO

nice chart man..will be using that...

this medium is coco fiber, considered hydro...

 

[JM]

couple more... np mate... ph is very important... as you can see by the charts...

i would say it was hydro if using chemical feed 5.8 is a good target but go with what it says on the nute bottle
if its organic hydro it could have a higher ph

 

[JM]

yeah.... agito knows his hydro better than me... i havent "gone hydro" in a whiile... lol soon again to run a small demo model for testing.. :smoke:

 

[agito]

I havent done it myself for a while and never organic hydro

I'm not sure who said you didn't have to worry about pH with organic nutrients, but that's not right. Especially with coir, as it's much more pH sensitive than soil. Maybe in soil it's easier to have a fluctuating pH because it'll help to buffer the pH, but when you're running a hydro situation, pH is very important because of the lack of buffering the medium will provide.

pH is a tad low and likely locking out N and P. With the addition of the Happy Frog to the Sunshine mix it's not a true soil less mix anymore. I'd try and get the pH up a little, maybe around 5.8 - 6.

thanx alot fellas!

didnt take in consideration the H/F...very true...

love the graphs JM...

GO claims you dont have to ph...also the mycorrhizae is also a buffer between the plant and the water/nutes.
