Hello, Im growing autoflowers. Do i subtract the ppm out of the water before i measure the ppm of my nutrients? I got told to do a ppm of around 550 but that does not seem right as that would be about 1 gram of maxibloom. Sent from my LGLS991 using Grasscity Forum mobile app
i feed at 1.2 EC, thats the EC of the base nutes. my water is EC .3 so my mix is EC 1.5 what is the EC of your water? If its too high, you may not be able to feed full strength. the plant might not be able to take the high EC of full strength Nutes plus the high EC of the water.
