Temps 23 C at night 28 lights on

Humid 50 ~ 65%

better pics and a more detailed description will get you help

plant in general looks healthy tho

Need a good description. Pretend we know nothing about your grow. People can help but they need to know soil or coco, nutrients given, tap water or RO water, etc.

If I were to guess without details, I go with early stages of Ca deficiency. seems to be common at that growth stage especially under LEDs for some reason.
