Today I increased the calmag to 250 ppm, and yes I got cheap when I was trying to follow your grow guide and got Gravel, which I think that you are right stinky when you say the gravel doesnt have enough spaces inbetween. I change my reservoir every week. Stinky will I be able to make it through the flowering period using gravel? Last week I got a little nutrient happy and put in 250 ppm of calmag and then 550 ppm of ionic bloom and that is how the plants started to look like this. Thanks for the help
