Your on a good path. With the 1 kg of weight gain I would not sweat it. Weight gets tracked over time and you are looking for a trend over a week or longer. Depending on the morning I can swing 2 kg when I wake up, but if I follow the trend over the week and see the average weight from 7 mornings is lower than the week before I know I am loosing weight, not gaining.
Also this is the first time you are taking steroids. You have to learn how your body reacts to it and different people are more and less sensitive to a given steroid. My wife did Anavar and actually gained 2 kg over 8 weeks, but her bench went from 95 lbs to 155 lbs over that period of time and all her other lifts also increased. That meant she was most likely building muscle. On the other hand my wife tried primo and her Libido went through the roof, she lost about 4 kg over 8 weeks, but also dropped down on her lifts 10-15 lbs each. Now she has a plan to try and run both together and see if she can get the weight loss or maintain and also get stronger at the same time. My wife can't handle Clen as even at 10 mcg it gives her a headache.
