Discoloration on a few leaves not sure what to do?

[BigEd001]

Development on a few leaves. Soil grow happy frog Robert Bergman nutes. White widow auto flower will be 5 weeks above ground come this Monday. Temps running 70 to 78 humidity running between 45 to 70. Temps are low at night to highs on daytime. Humidity runs low on colder days but stays around 50 most of the time. Not sure what is causing discoloration but other wise plant is growing very well. Wondering what it may be and if there is something I should do?

Other than the issue they look like you have been doing a good job.

It looks like a deficiency I'm just not sure what.

If I had to hazard a guess it looks like magnesium deficiency maybe

Are you talking about the lighter green on new growth? If that's what you talking about that's normal, plants just growing quickly it will darken up when they age a little. If it's something else I don't see it.

Oh maybe I see some patchiness on the leaves. Idk I'm color blind in green and red . (Slowly walks out of. Topic)

Worst case you can rule it out as a cause at least
