What is wrong with my plant?

[ArabianSarah]

First grow, one of the plants has yellowish leaves, still green but a slight tint. The leaves are also curled down a bit. What could cause this other than overwatering as I don't think I am overwatering and other plants seem fine?

Many thanks

Hi there, if you want help from the more experienced growers on here you need to give more info on your grow ,

To me it looks like you're growing in coco coir which has no nutrients , maybe that's why they are turning a bit yellow, how far are your lights? What lights? Feeding schedule? Temps? Humidity?Are you watering at the right ph? , coco coir should be 5.8-6.2.

I'm sure if you give a full breakdown of your grow help will be at hand.

Looks like too much heat or too much light. The bars in your first picture and the color of the light make me think you're running an HPS. That's a better light for blooming, but it can definitely be used in veg. They can be very intense though. For a seedling you might need it to be 4 or 5 feet above the top of the plants.
