Can anyone tell me if I should worry about this?

The yellowing at the top of the leaves? I'm growing under a 300 W led light but it's 24" away from the plant. Is it bleaching? Does it have a deficiency ? ( I grow in coco coir)

Anything would be very helpful , thanks!

I don't think it is the light. Has to do with fertilizers. What do you give her? and how much? otherwise healthy looking, buds need food and it takes it from the plant.

I highly recommend this book. There is a great section on nutrient issues (which is what you have).

Look up potassium deficiency and check what you're feeding her- possibly a little too heavy on the N/veg nutes and needs more for flowering
