Hey there could be a deficiency or a few other possibilities need a bit more information. And if possible post a photo of the whole plant to see if the newest growth is showing early signs of issue also. Are you growing in peat or plain coco coir? Any nutrients in the potting mix already? How close are your lights? Do you know the ph of your water? You can also use your grow question and get a bunch of growers to give you their opinion. Feel free to shoot me a message.👍
