Keep an eye on your pH... pH fluctuations can cause brown spots between the veins. If not brown but more yellow its magnesium. can also be caused by pH fluctuations but believe from your explanation its the former. Make sure your pH is between 6-6.5 for soil and 5.7-6.2 for coco. good luck

Can't really see with that light color but I'll give it a try:
-Check under the leaves for bugs. I had spider mites doing those marks on my plants before but might be something else.
-What nutes you're using? If not bugs I would say calcium deficiency? Is it possible? Without more info about your grow is really hard to guess.
-Also when a plant is overwatered for too long or has "wet feet" similar brown spots can appear and be mistaken for calcium deficiency or other deficiencies.

Leaves looking f’d?What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worseWeek 14

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.Leaves. Color - Dark-brown
