USAGE RECOMMENDATION
For a 20 ltr water tank
1 ltr = 20,000 ml
1:200 SEEDLINGS
1 ml nutrients solutions to mix with 200 ml of water
100 ml nutrients solutions to mix with 20,000 ml (2ltr) water.
FOR a 20 Ltr water tank (full tank of water) ---> 100 ml: 1/5 of the 500 ml bottle.
1:120 GROWING
1:100 FLOWERING
FOR 20 Ltr water tank ---> 200 ml: 2/5 of the 500 ml bottle.
1:80 HARVEST/FRUIT BEARING
The capacity of the cover of this bottle is 10 ml.
While the seedlings are still small, Instead of pouring in 100 ml to the water tank, I prefer to add in each cover-full of nutrients gradually once per week for the first month and 2 covers per week for the next two months. There having 200 ml for three months for a 20 ltr tank hydroponic reservoir.
Add in nutrients gradually to maintain a more consistent pH.

20220103 Monday 0800 Continuously heavy rain 4 nights.
If you observe some plants starting to dry up like this on the next day or the next few days after adding in the nutrient solution, it is likely the nutrient is too strong for them.
Add in water to dilute them.
Use lesser nutrients next time.
Once per week add in the nutrient,
Add water,
Check pH,
Check EC.
Check TDS,
