Can anyone help Iv bought a ec pen but don’t no how to use it I have checked my ec and it’s saying 1145 Iv used 2ml of A+B 1ml calmag 1ml humibooster ph is at 5.8 when I try diluting it with water the bit ec does drop much ?
Not sure on your pen but that reading may be equivalent to ec 1.145. So your running autos which I find top out at an Ec 1.2-1.4. Get your water and test that 1st. Write it down, eg mine is Ec 0.185. Then add 1 ml of each nute you use and see how much each one raises it by. From that you should be able to dial in how much of each product you want to use without exceeding the Ec. Good luck
