hey man, vegging on 24/7 is a great idea, really works well + it helps get that veg going quick. Thing is the plant will kind of go into overdrive, which means a faster more intense metabolism. fast metabolism means faster growth, faster growth means you need more plant juice if you want the plant to be healthy. You've just got run of the mill calcium and magnesium deficiencies from the growing too fast. Very simple to fix. Just get some cal mag , probably the flora micro works. See what the label says about feeding quantities , double that to reach saturation, then use that solution in a spray bottle and spray the plants once a day until they're dripping wet. This should fix your problem in five days or so. Hope this helps bro - merry christmas ! 🚀
