Since you have all three of the basic fertilizers made by the same company that makes the soil mix it is best to mix the nutrients in the amounts shown on the company's schedule.
I had been wondering why the plants would be showing a possible Phosphorous deficiency if you had the fertilizers. Putting one teaspoon of each fertilizer in the one gallon of water is the same as feeding 1/2 to 1/3 or less of what is needed. After several successful grows and harvests then you can start to develop your own schedule but trying to do it now will often end up with one or more deficiencies.
Put the right amount of one fertilizer in and shake the bottle and wait a few minutes. Then put the right amount of the next fertilizer in and shake the bottle and wait a few minutes. Then put in the third fertilizer and shake and wait a few minutes before watering. Use the amounts for the week of the plant's age.
Once a week put in the amount of Calcium nutrient and mix and wait. The start with the first of the three other fertilizers.
