4 part organic mix

I used bat guano,bone meal, kelp meal, and ewc to amend my old soil then mixed 70/30 perlite.. here's the results
I'm hoping this mix will last me all the way till harvest.

While you may have enough micro's left in the soil for this and maybe another run....I would have amended with some granite dust or another long term micro source.
Simply because I don't "know" whats they used for that in the soil in the first place....

If the plant starts to yellow in bloom Too much Bone meal.

I recharge home made organic soils (these get more organic runs) and soils I've run synthetics in too. I use that to run more synthetic's in...
When I recharge that soil. It is with organic nutrient source's. I make a nutrient "mix" like she does in that thread and recharge to a "base+" soil. About 25% of a full on water only soil...

Good luck
