Help Please: Weird New Growth

[Crownrawyal]

I’m a new grower growing some Master Kush from Nirvana Seeds. My plant is 5 weeks in veg, 28 celsius, with 50 humidity. I’m growing with fox farm nutrients in a 2x4 tent. I have a Mars Hydro 1000w led. I just noticed on my plants the new growth looks shriveled up. Anybody have any idea why? I’m using foxfarm nutrients every other watering and 6.0 ph water. Also noticed some of the stems on the fan leaves turning purple.

That almost looks like fimms recovering! Very strange. How far are your lights off the plant? Have you checked the PH of your soil or water? I've seen weird swirls before, they tended to grow past it if I remember. I'd watch those nodes, if they weren't progressing, I'd be tempted to chop that little node and see how the side shoots do.
