I was watering once a day just 1ltr each plant during veg slowly increased the nutes till they were ready for the full dose same on flower only flushed on week 3 then let them dry out and added my boost I can't give a ppm/ec I don't use a meter I just go with what the bottle says as a full dose and keep it below that till they look ready for it. (Ionic is what a used)May I ask what was your watering schedule and nuts Ec ppm
During veg and flower?!
How often Do you flush (if you do) ?
