Spots that only show in photos

hey there Dudditzou, sometimes that happens because the camera capture wave forms that get mixed up under the spectrum of the LEDs. it's good news though because you just caught the start of a magnesium deficiency and probably a P excess. the P excess is what will cause the yellowing towards the center of the plant and the magnesium deficiency is what will cause the yellowing on the sides of the leafs. Try adding potassium to even out your NPK ratio as well as adding calmag or just reducing your light cycle which is the root cause of these problems. Hope this helps ! 🚀

There doesn't seem to be anything I can see wrong. I would be tempted to lower the PH closer to 6.5 as ph 7.0 is a little high. I know its recommended Ph 6 to 7 but I find above 6.5 locks out some vital nutrient.

From the photos in your diary i don't see anything to worry about. Happy growing
