Help Please

hi please help about 2 days ago my plants started to wilt and the lower leaves turned yellow,i have removed the worst leaves but will my plants get better,what is wrong with them,any help please

Although yellowing of leaves can mean one of a thousand things, a deficiency in nitrogen usually appears as a yellowing of lower leaves. Since nitrogen is one of the most important macronutrients it may be a sign you need to supply more nutrition. Keep in mind some yellowing of leaves is relatively normal and is not necessarily a nitrogen defficiency.

You didn't say what you're using for a soil mix. Use the search engine and enter "Schultz's Potting Soil Plus." You'll find a great soil mix there.

You need to provide pictures or a lot more info in order for anyone to determine the cause.
