Ok I know a lot of members may not agree with this and a little trolling may come my way for saying this. If you really have a desire to grow go simple VERY simple. All you need to feel successful and able to do this is one decent grow. So do it Simple VERY simple. Get yourself a bag of Miracle Grow, some inert perlite, some correctly Ph’d water and have at it. As far as watering goes don’t ever completely soak the pot. Only put in as much water is is needed to keep the roots moist maybe a bit more. You want to make the roots grow out to find moisture. You have the lights and other equipment you need. The only thing you’re lacking is confidence. So, forget the nute regiments, ppm, training, etcetera and all of the complications. Nature will take care of nature. All plants want to grow it’s what they do. So stay out of it’s way. If you run into issues there are plenty of folks here that want to help. Also a shit ton of good stuff on YouTube. While the grow is going read, study, watch, and learn When you get tired of reading, studying, watching, and learning. Read, study, watch, and learn some more. Before you know it you’ll be sitting pretty with jars full of big solid dank and tasty buds.
Of course if you really want to let a plant beat you down we cannot stop you. Whatever you decide best of luck to you and yours.
