Too much light or too little feed?

So I think it was a combo of overwatering and low feed when the lights got more intense they tried to grow but couldn’t access enough nutes. The lower leaves developed some copper spots while I let them dry out and then started giving them full feed, overall everything is looking better. I need to get a handle on my watering!

Light stress from too much light or, The start of a Zinc deficiency (be certain your pH is within range in your soil.) Zinc deficiencies can show up with the plant is having root problems or if the plant is over watered, even if the pH is right and the zinc is there. Proper watering practices help plants grow healthy and avoid a host of problems!

Determining whether your plants are experiencing nutrient deficiency or light burn involves considering various factors. Here are a few insights: Nutrient Deficiency: A pH level of 6 for both the nutrient solution and runoff is generally within an acceptable range for many plants. Look for specific signs of nutrient deficiencies, such as yellowing leaves, discoloration, or unusual patterns. Each nutrient deficiency presents distinct symptoms. Light Burn: Lowering the lights is a good step, but it may take some time for you to see changes in the plant's condition. Signs of light burn include bleaching or yellowing of the upper leaves, especially those closest to the light source. Coco vs. Soil: Plants in different growing media may exhibit variations in nutrient uptake and requirements. Coco coir tends to require more frequent nutrient applications compared to soil. Adjustments: If you've recently made changes to your feeding regimen or light intensity, it might take a bit of time for the plants to respond. Keep monitoring the plants for any new developments.

Not enough run off and salt build up. Coco is not like soil and us treated much differently. Soil need wet to dry cycles for plant. Coco is always wet , and lower ph if 5.8. Coco is basically Hydro In a potter.
