TNC cal mag

[Goblin]

Hi there and good evening Gr420

Its been a while since I last posted on this forum. I mentioned over on the good morning / evening thread that I didn't know I still had an account on here until I used my email address to register and found that the address was already registered.

I've just started growing again after a very hectic start to the year.

I've been hunting for some cal mag and I went and ordered TNC's cal mag where I found a 250ml bottle for just under 8 pound

I was wondering if anyone here has used or is currently using this stuff, I can't seem to find much information upon it.. apart from its mention on another forum where not much information was issued.

One thing that concerns me, is it's amount of nitrogen. When I compare this to the ionic soil grow that I have its nitro content is higher with its 4% N value, Compared with ionics 1.8

So yea has anyone used this stuff. I've been using it already at half the strength = 1ml per litre as opposed to 2ml per litre.. I'm thinking that I wouldn't need to use the ionic soil grow as the amount of N isn't as high. And if I were to start using ionics grow nutrient I might reach a nitrogen toxicity issue. I just don't know..

One thing I can say about it, is that it seems to be ph stable.

Thank you very much.

Some people don't add cal mag or any additive at all due to their water already contains high amounts, mine does although woth LED grow I tend to still need to add something but I'm dry amending my medium.

Welcome or welcome back anyway lol.
