Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

Leaf problem
My leaves are looking strange? Can this be because the leaf hasn't fully unravelled/grown fully yet, or could thus be heat/nutrition. Added 2x pictures to see clearer 😁

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?
