Hi @KillerKthulu! You've experienced a Calcium deficiency, which can be related to a wrong pH range, lack of Cal+Mag in your feedings, or bad waterings (flooded roots). In soil, Calcium is best absorbed within the 6.2-7.0 pH range, so double check your pH-pen and make sure it's perfectly calibrated, and try to remain above the 6.2 value. I see that you have already solved this deficiency by adding CaliMagic, very well done, plants look 100% healthy! Let me know in the comments section if you need any further information, and happy growing mate! 👊

It could be cal mag or maybe when u watered it got a droplet on the leaves and light burned it. But your plant is healthy all over except that spot. Don't worry just monitor closely and take action if it progresses. Good luck

Plants look great you have no issues in a few weeks those leaves will be buried beneath the upper canopy of leaves. A few weeks into bloom you will begin doing some light defoliating from the lower 1/3 of the plant anyways. You should start using some cal /mag just before you start to bloom to prevent the issue before it happens once the buds start forming they will need the extra cal/mag for proper development and helps your plants deal with the stress of higher intensity of bloom lights.👍

I think it's just when you soul water on the leaves (especially with nutrients in) and the heat of the light kinda burns this onto the leaf, not harmful just be careful when you water them.
