Not sure of my feeding schedule with hydroponic nutrients

Hi All

I would really appreciate someone's help here with my feeding schedule as the nutrients that I have been using don't seem to follow the same trends as I have found with most nutrients on the internet.

The nutrients I have are hydroponic nutrients and come in 3 parts - Part A, Part B and a MPK Bloom Booster.

They are powdered nutrients and each Part gets dissolved into a 5 litre water bottle (1.3 Gallons)

I am growing in coco

The first part - Part A consists of the following nutrients and amounts:

Nitrogen N 68g/kg

Phosphorus P 42g/kg

Potassium K 208g/kg

Magnesium Mg 30g/kg

Sulphur S 64g/kg

Trace Elements:

Iron Fe 1284 mg/kg
Manganese Mn 299mg/kg

Boron B 373mg/kg

Zinc Zn 194mg/kg

Molybdenum Mo 37mg/kg


The second part - Part B is a calcium nitrate containing the following:

Nitrogen N 117g/kg

Calcium Ca 166g/kg


The third part - MPK Bloom Booster consists of the following:

Phosphorus P 227g/kg

Potassium K 286g/kg

I have attached a picture of the feeding schedule which really confuses me because the Calcium nitrate(Part B) value just keeps rising when surely I should be cutting down on the nitrogen?

The measurements are for each litre of reservoir water.

If anyone can provide me with some advice on how to use these nutrients effectively with cannabis I really would appreciate it as I really don't want to have wasted my cash

Specific nutrients for specfic stages of plant growth A&B in Seedling and Vegative stage and then MPK Bloom in flower weeks 2-6) stage, Start at reduced rates, Look like to much nitrogen that 185/mg/kag, consider stop using part B for onw eeek (flus if you want) then introduce again but at re-duced rates and feeding (once a week)

So you think I should use smaller amounts than which are indicated on that chart. Maybe half of the amount indicated on that chart?

What about for flowering. Should I cut out Part B completely? Part B contains the nitrogen.

Sorry I meant Part B contains the calcium

I would follow the companies suggestions. I can't see you having any issues being that you will never exceed 2.0 ec.
