hi cegceg4048 said:MgSO4 (Epsoms Salts) as 1/2 teaspoon included with the NPK. Although the trace element mix contains Mg, it appears to be not enough and we do see quite a bit of Mg deficiency. I believe this is one advantage Tropica TPN has over this powder, but so what? Just add more Epsom Salts.
hi & welcomeseawolf said:i'm new to plants and dosing, and i'm trying to figure out what i need to buy and how to mix it.
This post explained alot but i started getting lost after the first page
so far i have come to the idea that i need to buy the following powders.
kno3- potassium nitrate
kh2po4- potassium phosphate
mgs04- magnesium sulphate
and trace elements mix.
i plan to mix this with water in these quatities for a 100 litre (25us gal) tank with just over 3wpg lighting
in 600 ml of water to provide 12x 50ml doses
i will dose the trace elements on different days
now for the question.....Aqua essentials sell alot more powders than the ones listed above, so do i have the right ones, and do i need to add/ remove anything from my planned mixture?
You have everything correct. The other powders are there incase any other defficiencies show, but most people's tap water contains all the minerals required, except the main ones you listed.Always separate the CSM+B from the NPK because it has a tendency to react with the phosphate. You can dose the CSM+B as a powder or if it more convenient add 8 * 1/16 tsp => Â½ teaspoon to 200 ml of water and dose 25 ml two times per week.
Hi,ceg4048 said:Hi bazz,
No difference whatsoever mate. In fact I think Epsom Salts is actually the heptahydrated form MgSO4Â·7H2O.
