Hi I'm a pretty new grower on my 3rd now. I'm growing in soil, I've been using biobizz nutrients line which I've been happy with except the cal mag which I found had gone off after each grow in the down time, so I've bought advantage nutrients sensi cal mag extra.

Sensi instructions are 2ml per litre once a week. My question it that the region I live in tap water is very soft, it come out the tap at 45ppm. Do I still only use it once a week or should I add it with every watering?
 
what soil you useing? all soil will loose its nutrients and become a hydroponic medium basicly. unless you add organic amendments to it to keep it healthy.
try it at half that rate once a week and see how it go's. you can allways add more if it shows signs of a deficancy.
allways err on the side of caution, its easy to add more, not so easy to get rid of it once its in the soil

even with a ppm of 45 there's no way to know what those ppms are from. I'd suggest sticking with your nutrient line as they are one of the few liquid organic lines. adding in more inputs mid grow isn't always the best idea, you can find high quality filter attachments for your tap. this will bring your ppm low enough to mix your nutrients in.
 
Well I am happy with biobizz line, its literally just the cal mag I was finding was going off and was wasting money on buying more,

my previous 2 grows I didn't add cal mag till I started seeing deficiency but there were definitely cal mag deficiency. So I definitely need it, it already started showing deficiencies. It's just how regularly with this different brand.

It's just how regularly with this different , i havnt worked with biobizz but I've heard good things. cal mag deficiencies can be deceiving, my suggestion would be to maybe find an organic dry powder u can add to your soil, maybe this will act as a slow release and give you more time to relax.

this grow is only a few weeks old and showing cal mag deficiency. I'll be reporting in the next few days.

I use biobizz products most the way, light mix for seedling, then I pot up into their full mix. I also use worm castings, I top dress with ecothrives charge (insect fracas) and use their biosys which is a microbe tea
