@Dr. Who I have some living soil no till beds 4+ years i was thinking about using some big n sticky right now at transition and maybe once more closer to harvest, as well as maybe some potassium sulfate at the end. I don't really do any "flush" just water and some homemade LAB from unpasteurized goat milk, for the last week before harvest. Do you think this would do more harm than good?
Hmm, looks more like something to get money out of you to me.
If I remember right, potassium phosphite was originally used in fungicides. I think somebody noticed it added a bit of vigor to plants during heat stress and other environmental issues.
It gets put in some fert's that are used for high P need plants or defs.
Cannabis should not have any real need for that......Got a P def? Raise your feed pH and that's solved (as long as enough is available)
The kelp is likely used for the Humic/Fulvic's - bet you know what that does..... I again, don't see the need.
The carb's? Well that's simple...These are to get your soil more bio-active so the plant has better availability of nutrients...
I don't see it my self.
I prefer any supplementing I might do. During weeks 4-5-6 and sometimes 7. I am not a fan of high P at any time but, I do add some during the last 2 weeks, as I decrease the N.
Last week I simply use water - not as any way to reduce anything in the soil or the plant.
Simply because there is enough residual nutrient in the soil to carry me out and not use things that cost money - when I don't need to.
As a note: It take about those 7 days for the plant to even begin to show any feed change.... Never saw any yet in my runs.
