The Plant-a-lot Straight Grow sachet weighs about 20g and will add 1.1 EC to the initial EC of the water.
The Plant-a-lot Straight Bloom sachet weighs about 30g and will add 1.6 EC to the initial EC of the water.

pH & hardness
Plant-a-lot Straight Grow and Bloom is formulated for medium hardness water of (EC of 0.4-0.6) and the recommended dosages give the perfect pH value.
However, if RO water is used, then the solution will have a lower pH, and should be adjusted accordingly.
And if the water has a higher initial EC value, the solution will also have a higher than perfect pH.
Working with concentrate
To reach the perfect pH value with RO or very hard water, or to use Plant-a-lot Straight Grow and Bloom with an automated dosing system, the grower can prepare a concentrate which can be further diluted.
For the concentrate, a sachet is first dissolved in about 500ml of hot water.
The pH of this concentrate should be about 2.75-3.
For RO water the pH of this concentrate should be brought to pH 5.75-6.0 by adding pH-up.
Now the concentrate is strongly buffered, and can be used with RO water, or just to increase the EC of the working solution while keeping pH-perfect values.
If this concentrate is to be stored for longer periods, it should be in sealed containers.
