I grew with Fermented banana peels.
Wash peels
Cut in slices
Place in jar
Add water
Make sure they have water above surface
Lid on
Stay for 3-4 WEEKS (Fermenting)
Water should be cloudy.
If it goes black, toss.
About same routine as yours without the sugar added.
Cal mag, I had from Emilya.
Then coffee grounds
We got ourselves some good buds from the above.
If you add good organic soil and better lights to the equation... (I grew with led/cfl in veg and T8 in flower )
You have some killer buds in your hands
Eggshells and vinegar.
