Yes, it's quite common for cannabis plants to develop yellow leaves during the later stages of flowering, especially around the 8-week mark. This can happen for a few reasons, many of which are normal and not necessarily a cause for concern.

Curling leaves upwards, intervienal chlorosis, appears to be mag deficiency to me.

Si es normal que la planta empiece a poner las hojas amarillas ya que está consumiendo sus nutrientes, hermosa planta

Light stress or Nute Problem??
Would this be a light stress problem or a nutrient problem? Seems to be only the ones on the top so I'm guessing lights but want to be sure.

Single brighter/yellow leaves while flowering
Hi fellow growers, Again I have to kindly ask for your help. She's in week 7 now, the 2nd week of flowering. I've noticed only the two largest leaves to shift towards a brighter green, almost yellowish. I'm hoping it's because of the flowering but I'm far from sure. Thanks

Yellowing leaves
Lower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?

Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Maybe nutrient burn or?
My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back up
