I've had it happen to me a couple times when the girl was verging hard and fast, the leaves that grew while she was getting herself upright were twisted toward the light. The growth the next day was perfect. I've also had them twist when I had my light too close, which will create problems if not corrected, but aside from that I had no issues in my experience (which, I admit, is limited) when it wasn't the light intensity. Happy Growing! ✌️
