I have some Epsom salts but I've never used them before, would it be worth using any of those while I'm waiting for the canna?

I would dissolve 1 teaspoon in boiled water (small amount) then add that in 2 litres of water and add 2 ml/ per litre of veg feed to get them started. Canna mg is liquid epsom salts but it's measured % which I prefer. If the epsom dose sorts it and you're happy just dissolve and go.

Thanks @Oldbear :yep:

 

I'll give them some tomorrow. I've read that with Epsom salts it's recommended to only use them 2 or 3 times through the cycle, any idea whether I should stick with that or add them every watering from now on as the level in my water is so low? Or if anyone else has any thoughts on that? Don't mean to give you such a grilling!! :D 

 

Cheers dude

The danger with magnesium is without the correct ratio calcium isn't transportable. Magnesium is mobile, calcium is immobile and needs the relationship with magnesium to get nitrogen to the areas for photosynthesis. 

 

Have a look at Jeff Loewenfells (might be misspelled) books, Teaming with nutrients and Teaming with microbes. Great information to understand what is happening. 

 

Ask anytime mate :yep:

Hey mate, your optimal ppm depends on your nutes. I don't use OT but I'm pretty sure it's good in med- med/hard water. 

 

You want your calcium in the 150ppm range with magnesium around 40ppm

 

Anything above 120 for cal should be good in compost. Over 200 it's hard and you'll likely cause lockout on a schedule feed. 

 

I only use ppm to balance my water. I don't use nor recommend pH in compost. Once you know your water is good it should be just watch the plants and feed accordingly. 

 

Last tip, avoid RO in compost if possible as it is unwise to strip out micro nutrients as the micro herd love and need them. Find out what your tap water is for cal ppm and mg ppm and set that, you'll be sweet. 

 

@  me anytime if you have a q about water.

I have very soft water and my local water is:

Calcium is: 26.1 ca/L

Mag is: 3.4 mg/L

 

I'm currently using both soil and Coco having the issue in both. I welcome any advice you have. :) Or a general point in the right direction. Although i'm using GA Nutes.

 

@Freddy_Freekowtski Sorry for the post high jack saves me posting one myself.

OK your mg is low but not by much. If you're using GA customised nutes you're golden. If it's off the shelf, give them a ring and tell them your cal : mg ratio. They'll mix your feed to suit, job done 

 

To balance yourself 

 

Canna mono mg @ 7% 

0.6 ml per 10 litres water to get 3.5 : 1 ratio to start.
