Good stuff
I've had a sickly "tomato plant" that was accidentally watered with very low pH water and has been struggling to recover for over a month, she went very yellow, she's was flushed with good pH a couple of times and did improve but has been limping along ever since. I flushed again yesterday with appropriate pH water and fed her half strength Bio-Bizz Bloom + half-strength Bio-Bizz calmag in the last watering, and she's looking very sprightly today, her flowers have plumped up significantly overnight and the leaves are definitely less yellow. Going to feed the same to the remaining tomato plants today as her buds have now overtaken the plants that weren't poisoned with very low pH water. In future I'll stick with organic bio-bizz nutrients, all the other over-branded specialist nutes I've splashed out on haven't really shown such obvious improvements so quickly, and I want to go organic and eventually develop my own organic 'living soil' to grow in. I'd recommend Bloom & Bio-Bizz Calmag for sure. Their website has a table on how much to feed different plants going through different growing phases, there's also instructions if you peel back the label though they're fairly rudimentary. I downloaded the feeding table from their website, it makes it easier to quickly check when I forget what's what.

Very easy to use, instructions at 1ml per 1L of water
The best CalMag on amazon for your money. Always works wonders especially with just 0.01ml per Litre. 250ml - Plenty for my container garden (over 70). Fast delivery - bonus.
