What to do? Where am I at now actually? I’m lost and slightly discouraged

Looks good. Just make sure you collect runoff properly to find out if you feed her well. The pot must be raised on some rack to let the runoff leave the pot easily. To make a proper measurement remove any salt sediment from the saucer and the bottom of the pot with a moist tissue. Then water slowly to let the soil soak completely before runoff begins. Check the amount of runoff first. Ideally you want about 20% runoff of the amount spent for watering. Then check ppm and pH. Runoff 100-200 ppm higher than inflow means you need to reduce feeding until you get 0-50 ppm higher than inflow. Runoff ppm less than inflow means you probably didn’t wash out salts properly or the plant is underfed. Next feeding just raise ppm slightly, not more than 200 ppm at once. pH: if pH goes down there’s possibly salt build up due to drying out too much or the solution is too strong. If pH is raising that’s a good sign, meaning your plant is eating a lot. That works in general if you make no serious mistakes with feeding. If you need more details pm me.
