Plant is fine; nothing wrong. You will always get a few spots on leaves from water droplets ‘lensing’ under the lights and burning them like a magnifying glass in the sun.
Light green is indicative of new growth.

I’m so happy to hear that!!! Tomorrow Its watering day and I was wondering if it’s better to not put any nutrients this time but from what you saying I think it’s ok to put nuts right?From your experience it’s better to leave mute gaps or not?Thanks in advance!

It really depend on the nutrients and if you always feed at full strength or not? Also use TDS measurements on your runoff to determine if you can add more nutrients. Would also help to know the soil and nutrients you are using… and how old the plant is
