Hello, the leaves of the 45-day-old super lemon haze plant you see on the left have started to take the shape of claws. Can you help?

Yes. This might be a Ph problem, humidity problem or to hot in the tent. It might also be to much light intensity. So I would first look over the Ph in the medium! Water it and measure the runoff! If ph is wrong correct it with feeding it over and over again until the ph is right. Then set the humidity to 40-50%! And then 20-24 degrees. And maybe put the light up a bit and lower the intensity. Good luck my friend do this and they will be just find 😍😃
