i need some suggestions on one? i am using the whole bmo line of nutes, in pro-mix hp/ocean forest soil
.
Gjdubbz.... Use the Cadillac's of Flowering Boosters - High P Bat Guano or High P Seabird Guano. Most hydro stores carry them, you can even buy them on Ebay.
.
Just remember, their total PK value is always higher than the label. Example - a 0-7-0 has a soluble P value of 7, but a total value two or three times that number. The insoluble P will break down if you have micro-life in your medium.
.
So if using micro-beasties like SPT, Myco Magic, Plant Success, Sub-Culture...etc... count on them breaking down that other big chunk of P (if you topdress the crud - leftover from making it into a tea) or just straight topdress it.
.
I use two heaping tablespoons of High P Bat Guano (0-7-0) to a gallon of water to make tea. Then give each girl, one quart per gallon of soil in pots or a gallon (max) if planted in the ground. Two weeks later, I use four heaping tablespoons to a gallon of water. The day after I apply this feeding, I check the pH of my soil - since High P Bat Guano can push pH up.
.
Two weeks later, I drop back down to two heaping tablespoons per gallon, reduce it to one the next feeding - then none.....
.
If you topdress the crud from the first & third feeding, you will not burn your girls. I take the crud from the big dose (applied during the middle of the flowering phase) and put it in my compost barrel.

High P Guanos.......cheap, effect....available.....
.
Hope this helps.....
