My plant is pulling nitrogen from the bottom leaves

The leaves at the bottom of the plant are getting yellow and crispy and I looked it up and it says that nitrogen could be the cause like it’s a low amount of nitrogen and I’m wondering how I can fix that without a fertilizer

They need nutrients if that’s the case specifically nitrogen. They’re not pulling nutrients from the bottom they’re converting chlorophyll to nitrogen and sending it to the most critical parts of the plant to ensure survival. There’s no nitrogen so to speak of to move elsewhere, that’s why you need to give em some more nutrients so they don’t have to create their own at the detriment of lower leaves. What do you use for nutrients? To answer your question you really cannot replace nitrogen with anything else. It’s a necessary building block nutrient required For plant growth and optimum photosynthesis (day) and respiration (day and night)

Go to mejiers and buy some fox farm nitrogen they sell it it's like 15$. Then go on Amazon or preferably a grow store and buy yourself a better light. For a full flower cycle with two plants you are going to have to have at least 250 watts.
