Hey guys! Thank you for your replies :) I
have analyzed your opinions and came to the conclusion that indeed I can LST, which I wanted to finish, they are already a bit LSTed, I was more worried that the light was not enough as it is only 300 watts, but I guess that will be fine, as in 6 days I will get another lamp that is 600 watts and they won't suffer a lot of lack of light.
I tried using a LUX app on the phone, but it seems it is not accurate, so I cannot really rely on that, I will furher look into meters on the matter.
