Can anyone weigh in on what this plant is deficient in?

[DudeMcDoodleStein]

I have 2 of these Ruby Rails that I know are too big for their pots (2.4g). One is doing great, the other is what I would usually chalk up to “running out of steam” soil wise. I use these smaller pots with great success for smalll breeding/chucking projects but the taller sativas tend to run into problems around 10 weeks, last run one plants went 14. But I’ve seen this similar look on a few plants and while I’m not going to up my pot size I was curious if this is a specific deficiency that anyone recognizes as I might find a way to supplement in early to mid flower to push these larger plants to a nice finish.

What do you folks think?

How many weeks into flower are you?

 

[DudeMcDoodleStein]

This plant is 7 weeks and a couple days.

From what I can see, it looks like most of the chlorosis and necrosis are near the top of the plant. That would indicate light burn. So, that's my first guess. There is also a resemblance to N and Ca deficiency. It would help to see more of the plant, though. It would also help to know the environmental conditions.

I just harvested a couple plants. Shout out to Trust fall!

I’m a new grower and I’m learning about when to harvest and how to cure and all that
