Hi there, without more information, like the growing medium (i.e. whether it's pre-fertilized soil) and the EC values of your nutrient solution it's a bit difficult to say, but it looks like a deficiency to me..
are you using tap-water or RO water, and if tap-water, do you happen to know the EC value?
PH of 6.3 sounds ok for soil (if soilless, then it should be lower)
happy growing

Plantitas RegularesHello Friends!!
I'm a little sad 😢
I was gifted some regular seeds and decided to plant them, they're all growing wonderfully but I don't know which are male and female, is there any way to know the sex of a plant without getting to the 8th node?
