Yellowish color on most of the leaves and the condition did not change after watering. I suspect it's nitrogen deficiency or some pH problems. The plant is in pre-flowering, with sex being revealed. Will go into flowering soon. I watered it with 1.5l Any thoughts?

Yellow leaves at the end of flowering, should I worry?
I can use some help on this one. I am pretty new. The variety is called Hawaiian Staycation. It has done well and we are in the last week or so of flowering. It got a bit dry in the tent and the leaves really yellowed. I plan on harvesting next week, should I be concerned?

Nutrition deficiency or nute solution on leaves during watering?
Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.
