Deficiency?

Hey there! When you notice spots or discolorations on your leaves, you should always treat it like a checklist. Most of the time, it's not that there are no nutrients in the medium, but rather that the plant cannot access them. Here is how you can diagnose and fix this: 1. Check your pH levels (Most Important!): If your pH is off, it creates a Nutrient Lockout. If you are growing in Soil, your water/feed pH should be between 6.0 and 6.8. If you are in Coco/Hydro, it must be strictly between 5.5 and 6.0 (5.8 is the sweet spot). Check the pH of your runoff water as well. If it’s way lower or higher than what you put in, that’s your answer. 2. Is it a CalMag Deficiency? (Very Common under LEDs): If you see rusty brown spots, yellowing between the leaf veins, or curling leaf edges, it is highly likely a Calcium or Magnesium deficiency. Modern, powerful LED lights boost the plant's metabolism, causing them to shoot through CalMag rapidly. Fix: Add a dedicated CalMag supplement to your next feedings (usually 0.5 to 1.0 ml per liter, depending on your tap water's base EC). 3. Look at where it starts: Mobile nutrients (like Nitrogen, Potassium): The deficiency will show on the older, lower leaves first because the plant pulls nutrients from the bottom to feed new growth at the top. Immobile nutrients (like Calcium, Iron): The issues will show up on the brand new top growth first. Recommendation: Do not just dump more basic grow/bloom fertilizer into the pot, as this can increase salt buildup and make things worse. Check your pH first, adjust it, and if your pH is fine, add a bit of CalMag to your regimen. Good luck getting her back to health! ?🌿
