Hi my friend
You have 2 types of rinses
The extreme rinse that you apply at the end of your flowering in 1 single time (3-5 x the volume of pot time) Example: Pot 11Lx3 = 33L or 11Lx5 = 55L
For slow rinsing it starts 2 weeks before the end of flowering
For an optimal rinsing a lot uses demineralized water and others with tap water with Enzymes + a water set with a PH between 6 - 6.5. You will see that your leaves start to turn yellow
It is normal the plants will take in the reserves and feed it with the remains of nutrients in the leaves
Once the rinsing is done you let your plant rest for another week while your substrate dries well because you never harvest with moist soil
I just looked at your journal you are 10 weeks old at this point you can do a slow rinse
Every day you proceed with a normal watering with demineralized water or tap water
You give them 1 - 1.5 L of water for 7 days
Hope this helps friend & happy growing!✌️🏼🌱
