Thank you I’ll read it now

I’ll have questions for you I’m sure as I make the switch soon to COCO. I’m going to give it this a good read first thanks for posting it up.

You’re feeding in addition to worm castings mixed in.

Figured it out my ph pen was a POS so now that i got a new one next day and found out i was up around 7.1 ph so i was in nutrient lock up cause they doing fine today i cut alot of there foliage out there are stretching now but look alot better after a new flush at 6.0 ph with 50/50 nutrient mix rhey are praying today leaves are stanstanding striaght up

Chasing PH runoff numbers in coco??

The PH in the runoff you measure will not be what the actual suspended solution PH will be in the coir medium. This is because coco holds cations which contribute to the overall effect on PH. When you produce runoff, the solution is no longer in contact with the substrate and so the effect on PH is changed. The only true accurate way of obtaining a PH value of the suspended solution, is through whats called a 1:5 suspension test. Where a physical sample is taken from the media and processed appropriately for a ph measurement.

This is why we say not to measure run off ph or worse, try to control it. As you will be chasing a phantom because you are not getting the true measurement data. Coco coir is reasonably ph stable so all you must do is make sure the ph going in is correct.

Coco coir only has around 50% water holding capacity and half of that is plant water available. So it is paramount that you keep your media hydrated at all times, especially with those ammended with perlite. You also need to keep the feeding events constant and at high frequency to ensure optimal solution characteristics in the media.
