These guys should beable to respond with some good insight

Sorry, no idea. I’m a soil guy.

Probably not a good NPK, you’ll need to feed additionally.

If you want to make your own this is the basic mix.

If you want to start making your own good soil then your best to follow @garrigan65 soil mix and ensure its 30% Perlitre (because autos need airy soil)

As always thank you for your knowledge Will

The Mix

Here are the amounts we’ve found will produce the best-tasting buds and strongest medicines:

8 large bags of a high-quality organic potting soil with coco fiber and mycorrhizae (i.e., your base soil)
25 to 50 lbs of organic worm castings
5 lbs steamed bone meal
5 lbs Bloom bat guano
5 lbs blood meal
3 lbs rock phosphate
¾ cup Epson salts
½ cup sweet lime (dolomite)
½ cup azomite (trace elements)
2 tbsp powdered humic acid

This is the same basic recipe I’ve been using for the past 15 years. The hardest ingredient to acquire are the worm castings (especially since many people don’t even know what they are. FYI: worm poop). But don’t decide to just skip them: Be resourceful. After all, worms comprise up to ¾ of the living organisms found underground, and they’re crucial to holding our planet together. Also, don’t waste money on a “soil conditioner” with worm castings; source out some local pure worm poop with no added mulch.

I would be careful about soil recipes with a lot of peat. A lot of peat can cause low pH issues on its own, as well as lowering pH as it decays too.

While what your saying is true, and I personally don’t use either of the DIY soils I just buy fox farms happy frog and ocean forest, for autos they will only be I a pot for 11 weeks and these came from reliable sources although a competor so I can’t say the name. You can sub the peat for Bark Wich is a much more eco friendly source and doesn’t break down so fast although often needs to be screened.
Or if you have access to fox farms coco loco it’s Ph’d the same as soil but pretty much every other type of coco if I can recall is all going to cause issues if it has salts or is meant for soil less medium and thus a lower PH

Fox farm and other products like that cost a fortune in the land of OZ

Same here. I started back in October after not having grown since the early 1980’s. Big learning curve for me too.

If I was you I would be investing in water capture, or water well drilling dang you guys are burning up every year and just gonna end up the whole country being a dessert.

The only water you guys seem to have is guarded by saltys

That’s what happens when people won’t believe in climate change and just want to keep pumping shit into the air they fuck the whole show for a few dollars

I try and use fish emulsion in the grow period and guano in the flowering period but I’ll see how these shitty old seed go that I found around the house and sort out the bugs in my system and then I’ll fire up some gorilla glue auto flower and try and refine things to suit them
