A recipe for a one part 100% water soluble nutrient mix, using easy to obtain chemicals

Here are a few mixes I found they're not for lychee but I'll be using them as a starting point.

Vegetative mix:
1 US gallon R/O water
Calcium Nitrate - 2.2 grams *
Potassium Nitrate - 0.5 grams
Epsom Salts - 1.2 grams
Monopotassium Phosphate - 0.9 grams
Potassium Sulfate - 1.5 grams
Plantex CSM +B - .3 grams
* 3/4 cup of fresh sterile urine may be substituted

Blooming mix:
1 US Gallon R/O water
Calcium Nitrate - 3.1 grams *
Epsom Salts - 1.7 grams
Monopotassium Phosphate - 1.1 grams
Potassium Sulfate - 2.7 grams
Plantex CSM+B - .3 grams
* 1 cup of fresh sterile urine may be substituted.

How to mix if you aren't using zero or close to zero tds water -
1. Fill 1 gallon container half full.
2. Pre mix all ingredients in a small amount of hot water.
3. Add potassium nitrate and potassium sulfate to the container.
4. Fill container 3/4 full.
5. Add Epsom salts and monopotassium phosphate.
6. Stir well while adding calcium nitrate.
7. Add the Plantex-CSM+B
8. Top off container and pH to 5.8-6.4
9. Add .5 ml Seachem Iron if needed after mixing and pH'ing.
Failure to mix in the proper steps will cause calcium to precipitate out of solution and become unavailable to the plants. Water as close to zero tds as possible is highly recommended.

OR in a A-B parts form

For a 3 part concentrated mix (he did give that info, but I condensed the mixing directions and left it out):

Veg
Part A
1 US gallon R/O water
22 grams Calcium Nitrate *
* - You may not be able to keep 22 grams of calcium nitrate in suspension (depending on water purity). If this is the case, use 11 grams and double the dosage.

Part B
1 US gallon R/O water
Epsom Salts - 17 grams
Monopotassium Phosphate - 11 grams
Potassium Sulfate - 27 grams

Part C (micro)
1 gallon tap (chlorinated) water
30 grams Plantex-CSM+B

Dosage - 12 ounces of each part per gallon of reservoir volume.


Bloom
Part A
1 gallon R/O water
31 grams calcium nitrate *
*-You may not be able to keep 31 grams of calcium nitrate in suspension (depending on water purity). If this is the case, use 15.5 grams and double the dosage.

Part B
1 gallon R/O water
Epsom Salts - 17 grams
Monopotassium Phosphate - 11 grams
Potassium Sulfate - 27 grams

Part C (micro)
1 gallon tap (chlorinated) water
30 grams Plantex-CSM+B


Dosage - 12 ounces of each part per gallon of reservoir volume. These are just simple ratios. If you can double the amount of ingredients per gallon of water, use half as much per dose.
It can also be scaled down, i.e.- 1 quart water and 1/4 the amount of dry fertilizers will still equal a 12 ounce per gallon dose. 1 quart water and 1/2 the listed amount of dry ferts will equal a 6 ounce per gallon dose.

Mixing notes:
Part A
Add calcium nitrate slowly to water while stirring. Often it will help to heat the water. After mixing let the solution settle for 24 hours. If there is any cloudiness or precipitate, cut the solution by 50% with fresh water.

Part B
1. Fill 1 gallon container half full.
2. Pre mix all ingredients in a small amount of hot water.
3. Add potassium nitrate and/or potassium sulfate to the container.
4. Fill container 3/4 full.
5. Add Epsom salts and monopotassium phosphate.
6. Top off to 1 gallon.

Part C
Fill container with 3/4 gallon chlorinated water.
Add Plantex-CSM+B
Mix well
Top off to 1 gallon, again using tap (chlorinated) water.
Store in an opaque bottle, or in a dark place.
If chlorinated water is not used, this must be stored in the refrigerator.
