Am I gaining to much weight too fast?

I've just started getting into bodybuilding seriously in November 2019 I've been focusing on my calorie intake and protein intake, trying to get in 3500 calories a day eating protein rich foods while also making sure i'm eating foods high in fibre, although I wouldn't say my diet is healthy, I eat junk food very rarely as I oddly don't enjoy eating it.. I'm currently on holidays from work and I've been off for 4 weeks so I've been training 5 days a week doing a push/push/leg split, I'm training with all the main compound lifts deadlift, squat and benchpress being strict with form. I haven't done any cardio what so ever since I went on holidays on December 20th 2019 as I am a carpenter I do a lot of intense work for 8 hours a day I would consider that my cardio.
I'd consider myself to be a ectomorph, I have measured my weight gain from the 22nd of December till Jan 13th

I am 180cm tall
Dec 22 - 71.5kg
Dec 23 -71.0kg
Dec 24 -72.5kg
Dec 26 -71.4 kg
Dec 27 -72.6 kg
Dec 28 -71.1 kg
Jan 8 -73.8 kg
Jan 11 -74.2 kg
Jan 13 -74.8 kg
I weigh myself every morning after using the toilet at the same time, from what I've researched you can only gain 0.2kg of muscle a week, my strength has increased quite a bit in my lifts since I started but I'm worried I might be gaining too much fat then muscle, the question is does this weight gain look normal and healthy??
