So I've been doing alot of research on plant problems. My largest & oldest plant is looking sick (well, not that large & old-only 3 nodes). The bottom leaves are turning yellow and drying up (actually the 2 most bottom nodes). The top leaves are nice and green, and look healthy. The stem is also purple. I checked the pH and its between 6-6.5. I have close to 1,000 lumens 2-3" away from plant. I was over watering (with distilled water), but I stopped that. Now I only give water when the soil 1" deep is dry. This is the only plant that is doing this, and it really started to do it once I stopped watering it so much.

Could this be a N or P deficiency? If so, what exactly should I use to correct it? The plant is too small to start fert. I'm worried if I start to give it fert, it will burn the young plant.

I will have photos soon. Thanks everyone.
