hey there Ushangreen, so your plants went into overdrive due to the intense light schedule and need more magnesium. you can tell from the yellowing in between the veins of the leaves. They also need more calcium when they have little brown spots. The plant that has the yellow wilting lower leaves needs more nitrogen , you can tell when the older lowest leaves wilt and drop off. so to fix these it's simple, double your cal mag, and also have it as a spray you spray on spray until wet every few days until the problem stops spreading should be 7 to 10 days tops. Hope this helps ! 🚀
