Hey dude. I would say at this stage of your grow this is normal, this means the plant is diverting resources to bud growth and letting the leaves die off. This is a good thing. No need to worry and no need to do anything about it:

The light was fairly close, at 30cm. I've raised the lights to 60cm. It was also very humid, so I've opened the air vents .

Manchas amarillas Le han aparecido unas manchas amarillas en las hojas inferiores que no se muy bien lo que es. Tambien acaban de aparecer los 1° pistilos y no se si tendra algo que ver, me podrían ayudar? Carencia? Sobrefertilización? Se han quemado por el sol directo? Normalidad? Gracias

PH Fluctuations and/or Nutrient Issues?I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Leaf Discolouration I notice some leaves developing this yellow discoloration on the older growth, usually closer to the central stalk than the outside. The green gradually shifts to yellow going from mid leaf outward to the tip. I'm hoping it's just lack of sunlight from the dense foliage. Ideas?
