I am converting from liquid to dry ferts...I think.

So i am looking for a cheaper option now that i am almost all out of seachem dry ferts. and came across a place i can order some from!

Now for some questions:

Are these all the ferts i need or should i get more? Maybe there is one in here i don't need?
1 lbs. KNO3
1 lbs. KH2PO4
1 lbs. KHCO3
1 lbs. CaCl2
1 lbs. K2S04
1 lbs. MgSO4∑7H2O

And then there is this one that is also offered for 3x the price of the ones above do you think i will need this as well or what?
Plantex CSM+B - Mirco nutrients essential for healthy plant growth and survival.

So last question for now is:
How much and how often do i dose?
I have 2x DIY CO2 diffused though the canister filter, 2x 24 watt T5 HO lights, flourite substrate and the works. I have 0 algae in the tank atm, and would love it to stay that way, which is why i am hesitant about switching from my fert line now to another.

kno3 (k+n)
kh2po4 (k+p)
csm+b (micros)

this covers NPK + micros

if you have severe soft water you might need Ca + Mg, too. if you weren't using seachem equilibrium, you probably don't need them, anyway. plus... mgso4-7h2o is just epsom salts you can get at any pharmacy for way cheaper.

I have VERY hard water so i suppose CA + Mg.
So what does mgso4-07h2o stand for, If it is just epsom salts then why would i even really need to add it? I thought salt was bad to add to planted aquariums?

it stands for magnesium sulphate heptahydrate... which happens to be epsom salts and is safe for consumption and happens to supply magnesium (Mg).

when we think of "salt" we think of sodium chloride (nacl) or table salt. in chemistry salt would be an ionic compound created by reacting an acid with a base. in broader terms, salt refers to a crystaline compound. in essence, all of our fertilizers are salts when in dry, pure form.

yes... kno3 (potassium nitrate), kh2po4 (potassium phosphate) and csm is likely all you'd need and covers your macros (N [nitrogen or nitrates]),P [phosphorous or phosphates]+K [potassium]) and micros [a bunch of other compounds (salts) we need very little of individually].
