Need advice on gaining weight

I’ve been consistently using macro factor since April trying to gain weight because all my attempts before never worked. I’m 5’10 and weigh 132 pounds. I originally set up a MacroFactor goal to gain .5lbs per week, and the goal I was given was around 2400 calories. Each month nothing happened, the app recommended going higher and my weighed stayed in the range of 132-133. It’s now August and the app has me eating 2900 calories a day and I’m still seeing no change. I workout an hour Monday-Friday other than that I’m not too active. Another thing that could be causing problem is that I take adderal which apparently can speed up a persons metabolism by 10%. Anyway would be really helpful if someone can give me some advice if they had a similar situation, do I just jump the gun and try eating 3200, it’s makes no sense for someone my size to have a such a huge calorie maintenance.
