I found that no one answered, so I decided to answer this question myself
I have 3 plants, and I will probably start watering them every day once it reaches to middle/late veg.
If I'm going to be vegging for 4 weeks, then my plan is like this:
Germination (1wk): watering about 0.25 liters per plant, just until early veg starts
- Everyday: 3 * (7 * 0.25l) = 5.25 liters for 1st week
- Every other day: 3* (3.5 * 0.25l) = 2.6 liters for 1st week
Early Vegetation (2nd - 4th wk): watering about 0.5 liters per plant, just until mid-late veg starts
- Everyday: 3 * (14 * 0.5l) = 21 liters for 2 weeks
- Every other day: 3 * (7 * 0.5l) = 10.5 liters for 2 weeks
Mid-Late Vegetation (5th - 6th wk): watering around 1 liter per plant, probably gonna keep the quantity consistent from here, maybe will vary on late flower
- Everyday: 3 * (14 * 1l) = 42 liters for 2 weeks
- Every other day: 3 * (7 * 1l) = 21 liters for 2 weeks
All flower (7th - 13th wk): watering 1 liter all of this stage
- Everyday: 3 * (49 * 1l) = 147 liters for 6 weeks in total
- Every other day: 3 * (25 * 1l) = 75 liters for 6 weeks in total
TOTAL SUM & AVG OF WATER NEEDED FOR WHOLE GROW CYCLE:
Minimum: 109.1 liters
Maximum: 215.25 liters
Avg: 162.2 liters
Total nutes needed:
Minimum: 109.1ml
1ml - 1 liter
?ml - 109.1 liters
Maximum: 647.75ml
3.5ml - 1 liter
?ml - 215.25 liters
Avg: 377.425ml
Summary:
I can definitely pull my grow off with 250ml bottles. By my veg cycle of just 4 weeks, the bare minimum of nutrients I need is 109.1 milliliters.
