Plants yellowing

Wanting to know what should i do. ive noticed that a plant of mine is turning yellow fast to the point to where the leaves are drying up and falling off over night. what should i do.

It could be a number of things, but first thing that comes to mind is a Nitrogen deficiency. You shud get some nutes high in N. It will be the first number in the X-X-X listing. For example, you could get something like 15-10-10 and feed it when you water.

Pics?? Are you using just bloom nutes which are very low in Nitrogen? Are the tips showing signs of being burnt? Could be overkill with nutes. Many things are possible, post some pics if you can. Someone on here will be able to help you. A lot of knowledgeable people on here that would be more than happy to help!
