Is Mono Ammonia Phospate (MAP) good for cannabis?

izzy89started grow question 3 years ago

Hi friends I got some fertilizer Mono Ammonia Phospate (MAP) with N 12 and P 61 from work. It is used for agricultural crops like potatoes, wheat, grain, corn etc.. I've read it is good for root development and is also used at blooming stages...does anyone know about this stuff?

Waaaaaaaaaaaaaaaay to much phosphorous. Anything with P above 15 is scary! Not something for cannabis, maybe for depleted and raped agricultural fields, but not for sweet Mary Jane.

So that’s like a ratio of 1:5:0 then as far as NPK. A lot of ppl think you need excessive amounts of P in flower. So you’ll see a lot of bloom boosters with a shit load of P. Surely isn’t anything you’d wanna use on its own. Could be a bloom booster as the plant does like P in flower but you’ll also want plenty of K to go with that.. Basically it’s worth having I suppose if you work other nutes in with it for a more comprehensive regimen. Not much P needed in Veg

Runoff pH still climbing!My runoff PH keeps climbing despite lowering water pH. Plants look great but have red stems. Is it possible that the bottom of my fabric pots are saturated with excess Calcium and Diatomaceous Earth? Thus, raising my runoff PH. Soil meter reads 6.8 though 🤔

I’m out of BioHeaven I’m out of Bio-Heaven and I wonder whether it’s worth getting some more, given that I’ll probably flush the plants within a few weeks and only use water then. Plus it’s quite expensive compared to BioGrow, BioBloom or TopMax… Any ideas or maybe an organic substitute? Thanks!
