Hello all!!! First post here for me and about to start my first grow first let me say I am freaking out about my soil mixture and Nutes! I decided to go with promix HP for the full duration from germination. I will be planting an auto flower as well. So my confusion I guess is the nutes. When do you add and how often. What signs do I look for while growing to tell me the plants need more of something? I know the process will be trial and error and I hope to grow some beautiful plants like you guys soon! TIA for any input
