Hi guys, just starting my 1st grow and I am wondering if you can use molasses/treacle instead of cal/mag? I am on a very low budget and there are no grow shops near me. Molasses seems to contain high amounts of calcium and magnesium, therefore if used with tomato feed for nutes would this be ok? My medium is going to consist of multi purpose compost with a good helping of perlite. I am going to try to grow moby dick from sensai seeds. Any feedback on this subject would be greatly appreciated.
