It looks like your plants may have nutrient burn, likely due to the stronger concentration used in the 4-gallon mix. Here’s how to address it: 1. Flush the Medium: Rinse the soil or coco with pH-balanced water to remove excess nutrients. 2. Lower Nutrient Strength: Resume feeding at your original 1-gallon ratio to avoid overfeeding. 3. Monitor Growth: Watch for healthy new leaves, as older leaves may retain some damage. 4. Check pH: Ensure the pH is optimal for nutrient uptake (5.8–6.2 for coco, 6.0–7.0 for soil). This should help your plants recover. if i helped please remember to + me. :) and text me if you need anything else.

Is it possible you spilled nutrients on those leaves when feeding?

For me its not looking like nutrients burn. A nutrient burn starts usually with yellow leaf tips while the plant is dark green and the leaves start to roll down on the outside. But it can be overwatering or bad ph that caused damage on the root system ill search your fertilizer to fet more informations
