Most important thing I’ve found is just to learn from mistakes quickly, maintain checking ppm and make sure it’s within 300 of your inflow and adjust accordingly. Also probably most importantly, follow manufacturer guidelines on nute volumes. They are there to provide the best nute ratios. Just don’t go full dose start lower. Also, I put ppm for autos doesn’t need to be high. My plants in my diary are getting 500 ppm and look at the size of Dark Devil! Stunted the other two but I’m also learning 😂

Hey that seems very short for your girl. I would check the distance between the light to plant. You want to keep a constant distance the whole if at all possible. Try and go between 12-18 inches in your distance. That should help her get some growth. Always check your PPM going in and coming out. Always check your water/nute PH levels. Try and keep your PH between 5.5 and 6.5. Your light cycle should be 18/6 for veg and 12/12 for flower. That’s a good starting point for ya Happy growing
