Toxicity or deficiency???

Growing under led, 23.5 c temp , soilless medium, fox farm nutrients using sparsely. 15 gallon pots.Everything is fine until they started yellowing. Thank you in advance

Kinda late in the game but it looks hungry

Thank you for your response

Deficiency for sure, they look like they are deficient in cal mag and nitrogen.
