Tropic Mix Cal/Mag ratio

[ComfortablyDumb]

Hi Folks,

 

With Tropic having a Cal/Mag ratio of 2:1, what does this actually mean in practice please. ?

 

If my water is high in Cal but low in mag, say 6:1, does the compost bring my overall ratio back near into line, as in 6:1 x 2:1 = 4:1

 

Or am I just hitting the plants with twice the amount of Cal that I already have ?

 

While it's a nice compost, and I'd like to carry on using it, the cuttings I run showed def's that I've not had before with no amendment to my water.

 

Tia,

I enjoy using the Tropic Mix compost too

 

 

If that was my tap water,

I'd be adding either Epsom salts or mono Magnesium to bring your it up to a 3:1 ratio. 

 

I wouldn't worry about what's already in the compost. 

 

What lighting do you use in the nursery/cutting stage?

Yes, love the early growth but need to keep your eyes on the ball.

I did when using coco. GA said it shouldn't be a problem with their soft water nutrients beyond the odd epsom spray.

 

Also tried mono mag, then switched to compost thinking it would be more forgiving

Tried quite a few differnt composts of late with mixed results, same cuttings.

Nothing stressful, either T5's or HPS

 

Appreciate your response M8
