nitrogen or too much light for a cutting ?

Salut le jardinier ! pour moi ca va bien . bonne chance

first: yes, there absolutely is a thing as "too much light".. for flowering you need between around 400 PPFD to around 850.. anything above that requires (or should) additional co2.. a nitrogen deficiency usually starts with the lower leaves and not with the new growth, as nitrogen is a mobile nutrient.. so the plant can move it from where it's needed less (usually the older growth) to where it's needed more (the new growth), and given the yellowing seems to be more on the new growth here, it would indicate it's not nitrogen.. if you see yellowing on new growth i would recommend to check the PH level at the roots.. it seems you grow hydroponically, so that should be easier to check anyways.. light bleaching would be my second guess (especially if she's close to the light)

Hello.. Hope you are well.. I dont think its too much light tbh.. U can over expose plants to light but mainly wen they are seedlings /babies.. I wud personally raise ur nitrogen level n get ur feed to around ec1.4-1.8 if possible.. She's big enuf.. If anything it looks like a lack of light.. If she's bin hiding under another plants canopy u will get a bit of discolouration aswell.. Stay safe n gud luck with her.. 👍🍀
