Nutrients

And take like said by gmslave, buy an ec meter. I doubt that u have to put 5ml/l each of the 3parts nuts, but 5ml/l of them 3 combined. But i don’t use flora series so I don’t know how much concentrated they are. With the ec meter ( 10/20€ on amazon ) you can avoid problems and give the right anmount of nuts at your plants. It can be that you water is too hard and you will put less than 1/4 dosage in that case.

It’s based on your grow medium , light power and co2. If u does not use 1000w hid and co2 divide at least in half the dosage u read,first. Second, your grow medium, in coco/hydro the plant would have always theyr nutrient dose. In soil you give nutrient and then water 3 times and after that, u watch in what week u are and u give the right ammount of nutrient and again 3 times water . Have you understand how to read it? this is valid for practically all tables
