Hello ! Well you'r doing great 👍 based on your pictures the plant is healthy. I can see that 2 last weeks your ec was low (0.2) and you jumped straight ti 1.2 which is a bit brutal but if the plants can handle it it's all good. The only Tutankhamon I know is the one from Pyramid seeds and it's an Indica dom strain ( a AK 47 if I remember ) so if the lineage is the same then it is a short flowering indica with a hard stone and a sweet taste ( something like cherry ). As you checking your ec you should also check for your ph to avoid any ph fluctuation and burns. I hope it will help you 😁👍
