I currently have an indoor plant that was growing fine until the last couple of days. I noticed that the very first leaves had yellow tips then today when I checked on the plant it is spreading to all leaves. The box is 2x2x4 ft and I have a 60 watt led grow light that is running 18/6. The water is 6.5 ph and the temperature is 85 degrees and 40-50 humidity level. I started them in miracle grow seedling starter and then transplanted them into a pot with fox farm happy frog. It was doing great after the transplant but now the plant is having issues. I never gave it any nutrients just watered it when needed. Now that they leaves are yellow is there any hope for recovery? Any help would be greatly appreciated.
