Looks the the beginning of a calcium deficiency, It's common in soils that are more on the acidic side. I would get your soil around 6.4 and introduce some calmag at 1/2 dose to start.

All the best to you!

Flowering plants under LED sometimes needs Calcium supplemented as a necessity or they can get pretty fucked up quickly in flower, it starts off rusty spots, next it's brittle hard stems that snap like a twig made of glass then they're pretty much fucked as Calcium is very slow moving in the plant.

Yes just don't over do it. Once you get the pH sorted out your roots will be able to intake the pre-existing calcium in the soil.

It shouldn't be an issue, you have a healthy root system and they will "air prune" themselves given enough time. Put your pots on an elevation rack so more air reaches the bottom of the pots.
No need to worry, it happens!
