Hi-Yield - Muriate of Potash & Hi-Yield - Triple Super Phosphate

[saiyaneye]

A few years ago I purchased both of these. So I tried this last time, was not able to complete the grow so I am not aware if it's effectiveness. As little as I used them I have these bags for LIFE...lol

I understand that these are not acceptable "organic" fertilizers, I am trying to stay cheap, and maybe will get some organic liquid fertilizers but want to maybe supplement these in towards the last month of flowering. I know these are high or at least the Muriate of Potash is high in salt, which is pretty bad from what I understand, however I would only be using like 10-15 pellets per gallon.

Just want to try and use this as a booster, and want to know if anyone else has any experience with products like these?

Fox Farm ChaChing doesn't seem very organic itself. Just saying.

Are these granules water soluble? I was crushing them into a powder into small quantities and letting them soak for a bit in some water. I never think they completely dissolved. Maybe I could run them through a coffee filter after letting soak for 3-4 days in a milk jug?

90% Triple Super Phosphate crushed into powder (0-45-0)
10% Muriate of Potash crushed into powder (0-0-60)

I know other micro-nutrients are needed during flower, I just think of things too much it seems like

Triple Super Phosphate
Chemical formula: Ca(H₂PO⁴)₂•H₂O
Fertilizer analysis: 45% P₂O⁵ (0-45-0)
15% Ca
Water-soluble P: Generally >90%
Solution pH: 1 to 3

Muriate of Potash
Chemical formula: K₂O
Fertilizer analysis: (0-0-60)
Water-soluble: High

Why are you using them? I like to fiddle with NPK ratios, but you have to do the math to know what you're getting. You could easily mess up a balanced fertilizer adding things just because you think it's nice stuff to add. I made a spreadsheet which lets me know how much K2SO to add (to get a desirable NPK ratio).

I think it's more common to use K2SO4 to raise K. You can buy it on Amazon or eBay, 2lbs for $4 US. I've read that's better. Something about not having a chloride ion. And, you get sulfur which our plants like.

You seem to be looking for more organic sources of nutrients. To raise P I would use a high-P bat guano. Or, AK MorBloom, which is high PK. Or, maybe a tea using bone meal.

If you want more organic nutrients and be more aware of your NPK ratio (fiddle with it through the grow), look at my schedule. It's a balance between synthetic and organic. You don't have to "cook" a soil for months. You get the immediacy of synthetics, but also the kindness (to the soil biology) of organics. It's working very well for me.

I like being aware of the NPK ratios. That's something you might want to start with using the spreadsheet. Then play with substituting sources of N, P and K.

Well, I'm not necissarily looking for organic, I have some things available, I am trying to make this grow as cheap as possible and trying to get a good yeild. I usually do, I LST, Lolipop, and a little super cropping.

Those nutes are too hot and salty for pot growing. Super and potash work great outdoor in a hole sprinkled around the drip zone in flowering.

What I do is inexpensive ($1 per plant, per grow). MiracleGro is extremely inexpensive, about 30-cents. I link to a grow using it.

You can definitely do your own thing using bulk/raw salts, but use that spreadsheet to make sure you're staying in a reasonable NPK ratio. It's fun to vary the ratio and read your plant. It's a lot more fun that following a proprietary schedule.

muriate of potash is potassium chloride. It's not good because it provides a lot of chloride, which will compete with nitrates and phosphates. Consider potassium nitrate and monopotassium phosphate as your primary sources of potassium.

The potassium chloride would be good for storing your pH meter when it's not being used.

As for the triple super phosphate, I would only use it in soil. Keep in mind it also contains calcium

Ca(H2PO4)2

Normally in hydro you want to keep calcium and phosphate separated until they're in the reservoir. At least you can actually use the super phosphate. The potassium chloride will harm your plants.
