Hi guys just wondering if anyone has any experience in using treacle/molasses as an organic substitute for products such as cal/mag. I am using led lights and my growing medium is peat moss with a good measure of perlite and tomato feed for nutes, I am on a very low budget and I'm trying to use household items as there are no grow shops I can use too easily! Any help with this would be greatly appreciated.

I woud think crushd egg shells and epson salt woud be a good repacement for Calmag. You'd want to soak the eggshells over night and check the PPM to make sure you're not adding too much calcium

I agree with oldhippie64! Had a buddy that did that egg shell trick, took the rust colored spots right away!! Don't forget the epsom.

it takes a couple of years before eggshells decompose into a form that can be absorbed by plants, they are not a source of calcium for growing herb :peace:

What's wrong with CalMag anyway. That's good stuff - and it isn't expensive. It is exactly what they need, in an easy to measure and consistent strength.
Why make it hard?

well, if you're an organic grower, be careful you don't pic up a non organic cal/may or you'll kill all the organic stuff in your soil :peace:

if mixed with a heavily microbial tea, the non organic cal/mag may not affect the soils health too drastically. Most likely if the soil is super and super healthy, you should be fine :)

well, if you're happy to introduce an element of risk that you feel out weighs every other effort that you take to the nth degree along the growing path to ensure a healthy plant, then go for it :peace:
