Should i be worried

Just noticed yellowing on this leaf is it the start of an issue

Overall it looks ok. However, keep an eye on the small yellow spots and see it they change.
Might be a good idea to back of the nutes just a little until you are sure what is going on.

Thank you @tanlover442 im due for res change saturday and adjust the nutes thank again

She looks good overall just trying to catch an issue before it becomes critical

Check bottom of leafs, could be spider mites

What ppms are you running at? PH?

It is a good practice to have a bottle of lab grade 7 pH solution set aside for periodic checks of meter. I like to have my 4 and 7 solution for calibration separate because they can get contaminated going back and forth. She is off to a good start good luck.
