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
coastal20 Reviewed by coastal20 on . Vertical NFT Flowering Problems Hi, I have two plants that are 3 weeks into flower(12 on/12 off lights) and are looking sick, and im not sure what the problem is. Any help would be appreciated, I have set up two five gallon buckets on top of each other, using the bottom one as the res. I drilled 2 holes up through the top bucket for the drainage tube and for the watering tube. I ended up using gravel for the substrate. Im not sure if that is what is causing all the problems.
