My N deficiencies always started with bottom leaves yellowing if adding more N works for you great but if not completely flush it and then feed with what you were originally. Maybe try foliar feeding with Calmg if you notice any purple streaks forming on the stem it is Mg deficiency. Foliar feeding with deficient nutes are going to fix the deficiency faster than through the root zone

Hi there Jack! that’s actually Mg deficiency , you need more calmag and perhaps reduce your light schedule to reduce the stress and Mg requirements. Hope this helps ! 🚀

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8
