If you’re using RO water you’ll need to look at how much Ca and Mg your nutrients have In them.
If it’s around
5% Ca
1.5% Mg
then you may want to bump up the Calmag in the RO to around 150ppm to start with before adding anything else.
Please do me a favour.
Dont “flush” your plants for harvest its broscience and doesn’t remove anything from the plant.
plant below including already harvested buds have not been flushed and the buds have only been curing for approx 3 days funny how I didn’t have any harshness or “green” taste to them and I used nutrients right up to harvesting the tops.
