And one more planted today, bringing the grand total to 16 planted. 16 out of 19 germinated.
Good news... my legacy CBG mom now has 1 clone ready to plant in 1 gal pot, and some others that will likely root. Soooo... time to move the mom to the flower house.
Thoughts on Nitrogen
In another thread I've been inspired to delve more into understanding NPK and ppm. I've been using bat guano in my custom soil mix, which has an NPK of 7-3-1, as my primary N source. I calculated tonight that the amount of bat guano I've been using in the mix comes out to around 1,000 ppm of N.
I would really like some feedback on this... a reference point of 1,000 ppm N in my soil. Now, I've read that 175 ppm is sufficient N for veg, and too much N is not a good thing, of course. And I've seen other numbers, such as 250 ppm. The fertilizer comes with an application rate that works out to around 300 ppm.
So... some nuances come to mind, one of those being that if I'm relying on the soil to fertilize the plant, through most of its lifecycle, then starting with 1,000 ppm is maybe OK. Another thing... how much of the 1,000 ppm is actually available to the plant? This is all very dynamic, because you've got multiple factors determining how available the N is to the plant, including: pot size, amount of beneficial microbes present, age of the plant, size of root mass, etc. And, there's probably something going on with the bio-availability of the N, i.e. it's chemical form in the fertilizer, and how readily the plant (plus microbes) can utilize that. And yet more complexity... the ppm of the other nutrients involved in N utilization (Fe, Zn, Mn).
Any thoughts?
