Feeding in flower using coco?

Honestly. In flower it depends how big the plants are, and how thirsty they are. I used to feed every day but now I feed every second day. It honestly is half the effort for the grower, uses half the amount of nutes... never follow manufacturers instructions as it's just too harsh at times. buy I normally feed about 1.5 liters every 2nd day in flower. Buy a moisture meter or veg trug from Aliexpress... takes the guessing out of it.

Ideally twice a day to @10% runoff or a little more, but once will do as its all I can manage myself and we do ok. Might want a bit more runoff at once a day.

@Staypiffin You should use the technique of checking the weight of an unwatered pot vs a freshly fed one to ascertain if and when the plant actually needs to be fed or watered. I would say that once a day would be ample as you need to allow drying time between waterings for oxygen to be able to reach the roots
