Is this nute burn or deficiency? PICS

More and more leaves are beginning to look like the second pic. They turn light green and then yellow and then get those spots. What could this be?

anyone ?

could be nitrogen diff,,,it happens to most plants as they go into full flower.... but some else may have another opinion

What stage are you in and what nutes did you give? Have you flushed them? It could be nute burn or a deficiency depending on what you have done.

Possible Ph problems. What is Ph? Should be between 6.5 and 7.5 for soil

those look like ph spots. what is your ph at?

ie either nute diffeciancy or ph problems
