Phosphorus deficancy, need advice!

Hi, I need alternativ solution to a phosphorus deficancy problem. Without going to much into why, its an issue getting decent ferts n such.

I'm hoping someone know of a easy alternative way to get upthe lvl of phosphorus without adding any significant lvl of other elements.

I've been looking at lowering the ph abit too (7.5 to 6., and found that I could use a drop of phosphoric acid. Would that help fix a phosphorus deficancy as well?

Try bone meal if your after strictly P or you could go Indonesian bat guano -.5N -12P -.5K,never tryed phosphoric acid to lower Ph i usualy flush if i get To high on Ph.

Actually that was from the grow video link for soil/flowering (phos acid), tho i doubt it my self it would fix it. The thougth dropped into my head since im trying to figure out how to add.
I doubt i can get my hands on bat guano stuff, but that bonemeal thing sounds interesting. And yes, its stricktly phosphorus im after. Gonna go to the local pub and get drunk while thinking about it.
Maybe some of my friends know where i can get my hands on some bonemeal. Thx for the tip!

Hawaiian Punch "Green Berry Kush" has 173 mg phosphorus per 12 ounces.

Yes, I know it's actually Rush, but it just sounds so right.

Kelp meal or extract. It's a lot faster acting than bone meal, although bone meal is what I prefer.

yes phosphoric acid would work but you have to check concenttration or else you might lower it to much. or else try to buy phosphorous pentoxide(anhydrous of phosphoric acid the same way as supplied into feerilisers) from a laboratory store and ass around 300mg to 500mls of water

Oh please don't do that! Phosphorus pentoxide reacts *violently* with water. I was THERE. Stick with phosphoric if ya must.

Fertilizers quote phosphorus content as P2O5 equivalent, but that doesn't mean for a hot second that they use actual phosphoric anhydride to compound ferts. They also quote potassium as K2O, which as a real compound is strictly a laboratory curiosity.

Cannabineer, I'm glad it was you who went there. HELLO!!!.......anhydrous!!!. And if you don't know what anhydrous means, don't be screwing around with chemicals you don't understand.

My bat guano has 12% phosphorus and trace of anything else. (.0.02 or 0.05) I didn't want to keep adding other nutes as I am the queen of nute burn. Since this is my first time w/ hydro, I see my ph drop as nutes are being utilized daily. (that daily inch or two of growth doesn't happen by osmosis) My home water ph is 7, I am keeping my solution at 6.5 right now and adjust accordingly. It only the 3rd day of growth.

That is exactly what I have ~ Indonesian bat guano.

I was under the impression that the OP was in soil?? Please excuse the assumption.

Jack you correct

Update; Gonna go buy some guano. Did some experimenting with water and various stuff i could get my hands on. The result was a bit suprising. (screwing around helps x) Anything I tried mix into the water would decrease the ph, wich lead me to try with only 2 drops of the organic fertilizer i got. It went from 7.5 to 6.5.
So my conclusion, im going to get the guano and mix it with the fert i got in VERY small amounts. Thx for the replies

Edit: And yes! I found a supplier of bat guano
