Please help me diagnose this issue

Hello community, hope everyone is doing great.

I just arrived from a 2 day trip that turned into a 3 day thing, so my plants are craving for some water and food. Thing is that i just noticed that one of the plants, the Royal Gorilla (5 weeks into flower) has some yellow spots in the leaves now. This is my first grow so im not sure if tis is a calcium deficiency or a general nutrient deficiency. As im about to feed them it would be great to know if i should just supply some Cal Meg of should i just increase the amount of nutrients in general.

Any advice would be super appreciated.

Do you have the ability to check the PH and PPM of the runoff? At first glance I would guess some sort of lockout or deficiency. Following 🪴🤙🏻🤙🏻

@atnupacas The PPM going in won't always be the PPM of the runoff. The 1112 PPM that you mention should be ok for flowering but some phenos want more. I sometimes go upwards of 1600 PPM when in flowering. On another note, reading how you say it's the top of the leaves only makes me suspect it's light burn. I'm glad to see you increased the light distance. That may very well have been it.
