Hi my friend I have noticed with the apricot it's pretty slow but the temperatures are to cold I would say . I have mine at around about 27c and nighttime temperatures 20 c. I would invest in a small heater for wherever you have your grow. With the lights 300 PPfd is too small for your plants .it's best to invest into something like Mars hydro ts1000 I only paid 95 pounds for mine . With the pH if you go on Amazon and type in pH pen you can get one pretty cheap but don't get the cheapest .also you will need PH down I recommend xpert nutrients PH down for that or biobizz. So yes I put it down to being too cold the pH not being right and the strength of the light other than that I think you got it good 👍
