Somebody041.... Organic nutes will register on pH meters. When you mix them up, they will change over time (either going up or down - a lot depends on the water you mix them with).
.
You've probably heard that TDS meters don't help much with Organic Nutes, that is true. You can't read Organic Nutes with a TDS Meter like with chem nutes to determine feeding strengths.
.
With organics, you have to follow the label on bottled stuff. Or if making your own, follow receipes already worked out by others through trial & error.
.
For coco growing, you need your nutes in the 5 to 6 range of pH for best results. Shoot for the middle of that range and it's all cake.
.
It helps a lot to read the pH of the runoff twice a week. Just take some water with a pH of 6 and pour it through until you get runoff. Take that runoff water and check the pH. Did the number go up or down from the pH of 6 your poured through ?
.
If it went down, you can make a mild High P Bat Guano Tea and add it, instead of a pH up product.
.
If it went up, you can make a mild High N Bat Guano Tea and add it, instead of a pH down product.
.
You can use pH up & down products (in moderation) in organics, but I prefer to use amendments like guanos to balance things out. Use of pH up or down products from a bottle, as a general rule, equals the death of some micro-beasties (not all).

Hope this helps....
Keep it Real...Organic....
