(relatively) heavy lifting at a young age, parents concerned

[BuildEyal]

I've been lifting for almost 8 months, just turned 16, built my way up to 100kg squats and deadlifts WITH CORRECT FORM, never had any pain except for this one time i started a squat session and on the second rep with 70kg, it hurt on my right knee (and it was after 10 days i couldn't go to the gym). The pain went away the next session.
Told my parents about the 100kg lifts in excitement but they reacted really badly, getting all worried and demanding that i'd lower the weight to 80kg max and never surpass it, saying that it'd stunt my growth which i know is bullcrap, and that it'd hurt my back when i get older (which might be true, but thats a sacrifice that has to be made, im loving lifting like nothing i've ever done in my life and i want to progress and get stronger more and more)
I dont want them to be mad at me, but i dont want to drop the weights and basically stop progressing...
Anyone handled such a situation at the past?
If so, what did you do?
Is the heavy lifting hurting me?
I dont feel pain aside from the actual muscles that are working

What are you rep ranges? And, what are your goals?

 

[BuildEyal]

squats - 4 sets, starting on 70kg and raising by 10kg each set (70-80-90-100) each set 10 reps, except for 100kg which is to max (around 8 for now)
deadlifts - 4 sets, 1 - 10 reps with 60kg, then 3 with 100kg usually 5-7 reps, then 1 rep of 140kg which is max for now
main goal is building an aesthetic physic (which i have done to a certain extent. also get strong, i enjoy seeing my abilities rise and rise
not planning to be a powerlifter or strongman.
btw height is 1.73m and weight is ~73kg, 11-12% body fat

An important step would be to take video of your squat and DL form in order to become aware of any areas that need improvement. You can compare your form to western barbell club videos on youtube to be sure. You could also increase your rep ranges to 12-15. The slightly lighter weight will also help you make form improvements.

your parents are ignorant as are many parents out there. weightlifting does not stunt growth.

just another old wives tale. almost as stupid as the one where if you go outside in wet socks it will make you sick

Your parents should watch Pumping Iron with Arnold

My shoulders are quite fucked from doing too heavy of sets at a younger age, not knowing nearly as much as I know now. Be careful with sets that are heavy for you, you won't feel it now, but in 10 years you will regret not doing everything with proper form. Use a footing and form that is right "for you". I have decent form in my dead lifts, although I know I'm not doing it by the book, but I also don't do it by the book because it causes way more strain on certain parts of my body, when I know it shouldn't. (If it hurts, don't do it; plain and simple). However, there are certain things you should always do like (keep a straight back and always close out the deadlift to the fullest extent i.e. shoulders should be pinched together like you're trying to squeeze an orange and you should lock it out for at least 1.5-2 secs.), but your stance, width of your stance, and the width of your grip should be what is comfortable for you. Same goes for the squat, go balls deep on your eccentric contraction keeping your weight on the heels of your feet and a straight back and when you do the concentric portion of the lift try and hip hinge your hips up and outwards towards the end of the lift, your back should still be straight).
