Your right mate, very hard to get what we need, 379 km to the nearest good town with choices.
Online shopping is an option but dang expensive, by the time you add postage.
Thanks though for your input.

How hard is your water? I’m guessing well water. You may want to pick up some cal mag to introduce additional magnesium to your soil. It kinda depends on the hardness of your water. Not a lot of N in the first bottle. Probably though with good soil prep in your hole that you won’t need much until flower.

Ooh, good call on the Epsom salts! Might be way easier to find. The OP said he’s ordering a meter. The Apera is a fine instrument. Just remember to get some standard reference solution and ph up and down.

Yep you’re right we do have well water. Over here we call it bore water.
It is high in calcium so I guess it probably is hard, so I’ll give the Epsom salts a go.
Can get that locally.
Thanks guys for your help.

I hear you! I live in rural Alaska. I’m 110 road miles from the nearest town. Everything I get is mail order, except my soil. Amazon prime is my lifeline.

Could be an iron deficiency. Canna has a first aid for deficiencies guide that will get you pretty familiar with most common deficiencies. I picked it up at a local hydro grow shop or anywhere they sell canna and more than likely Google.
Cheers,
PH in the pots are 5.8-6.0
The water it’s self is reading around the same.
Thats a bit low for your girls in soil you wantvto be 6.3-6.8
I would get the ph up when you watet oe feed
I keep mine at 6.5
