safe to use old guano?

[rayco]

hola
recently a friend of mine gave me some liquid guano which i diluted accordingly in a 1.5l bottle of water. I only needed half of it at the time so i stored the rest in a dark corner indoors for a good couple of weeks. The other day i watered the plants with the rest adding some normal water. It wasnt till it flowed out that i realised how bad the smell was. It sort of smelt like rotten bird faeces and urine. A very strong and unpleasant smell.

Im worried that because ive left it, it has rotten and may be bad for the plants. I hope it hasnt become really acidic/alkaline for example and is gonna damage my plants...

can anybody advise please? Ive bought some fresh liquid guano in the meantime (for next week).
Thanx!

The stinkier the better, you definitely need to check PH tho in case it's rediculously low or something, and adjust it, but guano is very stinky anyway, and the stinky is good

i was actually reading the grow bible on the shitter this morning and it said that guana can last a longgggggggggggggggggggggggggg time.


the older it is the more phosphorous is has and the newer the more nitrogen


as far of already mixed with water, im unsure


if it smells worse than normal i would imagine its prolly not a good idea


better safe than sorry

Is phosphorus guano a good, absorbable source for phos? I'm using it on a mostly sativa that takes 7-11 weeks and I'm a full three weeks into flowering and it doesn't seem like the buds have grown much. And, they're starting to turn colors, hopefully not dying or anything.

Its excellent, Budswell brand is very popular for that. Don't use it in the last weeks tho, or your bud may taste a little shitty if you know what I mean..
