Hello, can anybody tell what is going on with the yellowing leaves in the attached pic? It's yellow spots on the leaves, with some leaves being about a third yellow and starting to curl and dry up. We have 7 plans and it's only happening to two of them... We're growing in seed raiser soil (contains a small amount of time release fertilizer for seedlings), and the area gets to around 38 degrees after several hours under lights (working on better vents, just mentioning in case it looks like a heat issue). Thank you for any replies, I know this question must come up a lot, it is just hard to find threads with people growing in the same conditions as us. !! Also, photo was taken under HPS and photoshopped to try and look real. Imagine if all the greens were typical marijuana greens, and the markings on the leaves are light yellow. Thank you!
