First sample, end of week 4.
Second sample, end of week 10.
Looking better numbers wise at the end. I have plants vegging in the bed right now, sucking up all of that K.
As Jidoka noted earlier, K deficiency is a real thing as plants mature in veg. If you can get the Ca, B and Si into the plant early, a good sign it all worked is the K def. Just be prepared for it. I bring K up at the end of veg and then transplant into the soil bed that is saturated with K from the last flower run. This along with foliar/ drench Ca gets roots to explode quickly into the soilbeds.
This is how I run my LOS/No-till style soil bed. My garden for my personal...
Jidoka, you have a sample from one of the big name coco's? Or is everyone running direct source coco now?
