Growing on a tight budget

[Goonie Goat]

i did study it over 10 years ago haha. once upon a time i was working in the commercial hort industry.

https://bbabio.com.au/products/max-phosphorus is the product just got given a tester from a hydro store. it's just Bacillus megaterium
, in the past I have used b amyloliquefaciens
I have only grown in coco for most of my life and still do. I am personally not a fan of living soil

That looks expensive. Yeah coco is the best I'm just a stingy prick who didn't know what to do with all the rootballs I had from previous grows lol.. I'm pretty basic when it comes to the numbers of things, so let me know if my P ppm is too high before other members here burn the shit out of their plants

I just have experience working with the hydrobuddy program. With it you start with a target ppm of each elemenant, add which fertillizers you want to use then it will tell you how much to add. Not sure if you can work backwards with it.

I can tell you it says 0.47g/ L will give 100ppm of ammonical nitrogen

personally i have been trying to get close to these numbers basically using them as a guide.

If I'm reading that correctly then it seems like I'm redlining on ammonia?.

I'm not seeing any terrible burns or having any lockout issues so far, only damage is from plants growing into lights and getting fried that way. Google reckons 60ppm ammonia is safe, so I guess I just need to cut my 40g dose down to 20-25g

I'll begin tapering down the MAP anyway, they're close to the ripening stage. I wasnt too far off thankfully with prior amounts of 30g or so. Time to change the recipe up again

I'd be careful depending on how far through flower you are it may not make the biggest diff. But honestly I'd stick with MKP.

I don't add much MKP in my mixes really and don't seem to have any P issues. Maybe the extra calcium chloride might be antagonizing P a bit.
