Getting a few lighter patches on some of the leaves (in the last 2 shots) and not sure what is causing that... possibly the cold? Any help would be much appreciated!

Hi @Shinsimilla! I see two possibilities here: either it's a pest-related issue, or it's nothing to worry about. I've seen this kind of mutation a few times in my previous run and in other diaries, and it was a natural genetic peculiarity affecting the first leaves, then it disappeared as the plant grew up. But in other situations, this could come from insects, especially thrips and/or leaf-miners. You should establish a pest-prevention strategy while she's in veg (by diffusing essential oils, spraying neem oil, deploying ladybugs or any relevant solution to repel all unwanted invaders). Take a deep look onto and below the leaves with a magnifier, look for thrips or any insects, if you don't see anything then it's the 1st option, you can relax and watch the new leaves grow without spots/marks. But the pest prevention strategy remains relevant! Hope this will help, let me know in the comments section if you need anything, and how it evolves with time. Happy growing! 👊

It looks like just a leaf mutation but I would play it on the safe side and start adding some extra Cal/Mag with a good silica product to help build stronger cell walls in your leaves and stems. It's just good preventative maintenance. In a few weeks your new growth will probably look fine. Hope this helps.👍

Yes I would say they are starting to show stress from the temperature. One solution is to use flat rocks that will stay hot after baking in the sun and pop your plant on top at night. Hope this helps a little.

Ya man those colder nights can wreak havoc on the tiny girls some times , it don't look like nute problems and ya I would just say some small stress wouldn't worry about it keep up the good work one of my girls had that on the second set of true leaves and I had cut them off was blocking light so I didn't think much of it ,your nutes ain't that high so ya should be fine and good luck
