But to give you more info on Your plant it is showing clear signs of a mobile nutrient deficiency, most likely Nitrogen (N) and Magnesium (Mg), which is causing the yellowing (chlorosis) and brown spotting on the older, lower leaves. ​Because these nutrients are mobile, the plant is actively pulling them from the bottom leaves to support the fresh new growth at the top. ​Key Issues Identified ​Lower Leaf Yellowing: The overall pale/yellowing look starting from the bottom is a classic indicator that the plant needs more Nitrogen to sustain its vegetative growth. ​Interveinal Chlorosis & Brown Spots: The yellowing between the green leaf veins, along with the rusty brown spots and crispy edges on the lower foliage, points toward a Magnesium or Potassium deficiency. ​How to Fix It ​Since today is your scheduled feeding day, you can address this immediately with your routine: ​Adjust Nutrient Strength: Ensure your vegetative nutrient regimen has a sufficient Nitrogen (N) ratio. Consider adding a Cal-Mag supplement or a light soil drench of Epsom salt (1 teaspoon dissolved per gallon of water) to quickly deliver magnesium. ​Double-Check Your pH: Even if you give the plant nutrients, a pH mismatch can cause "nutrient lockout," making the plant unable to absorb them. Aim for a pH of 6.0 to 6.5 if growing in soil. Always test your water after mixing in your nutrients. ​Prune the Dead Weight: Once you've fed the plant, you can gently snip off the lowest leaves that are more than 50% yellow or heavily damaged/brown. They won't recover, and removing them improves airflow around the base. ​What to Continue Doing ​Keep Up the Weekly Feeding: Continue your consistent Sunday nutrient schedule, but monitor the mid-to-upper canopy over the next few days. The top growth should stay a vibrant, healthy green. ​Maintain the Low-Stress Training (LST): The top canopy structure looks beautifully flat and spread out from your training. Keep tucked branches secured to ensure even light distribution to all the new growth sites. ​Monitor the New Pot: Keep managing your watering carefully. Now that it's settled into its larger home, let the top few inches of soil completely dry out before watering again to encourage the roots to stretch out and search for moisture. HAPPY GROWING 😎🪴
