Try increasing your nutrients slowly. If you notice growth changes within a week or so, you know it was the food. I had issues with small plants, weak stems, and semi drooped leaves. I was scared to feed over recommended dosage, but once I just trusted the signs of the plant, I knew something had to be changed. I saw no discoloration, other than light green leaves. I started increasing the feed strength with every third feeding. I didn't increase by much, maybe 1/8 teaspoon with each increasing. Finally, the leaves were dark green and I started having lush and rapid growth. Keep going until you see just a slight amount of burn, and then back off. I only recommend this in the veg stage.
