I don't have an answer for your immediate problem. You could be overfertilizing. But I can see future trouble ahead, which is bunching so many plants in the same container. I Can't tell how big or deep your containers are by the pics, but I find that one plant per container does better than 3 and 4 plants competing for space in one container.

They are super huge containers I was ganna thin it to 2 but they look so poor was sure which to thin out.Here is a pic of containers they hold 3 bags of dirt they huge.

They are big, indeed. But you will find that plants that don't have to compete for space simply do better. Experiment. Do what you are doing, but try one or two plants by themselves, and then compare the results. I don't know how much ezxperience you've had, but you will find that plants given ample room simply grow bigger and bushier and healthier.

I think your soil may be your problem. When you grow plants in pots you need to use about 50%-75% quality potting soil and then 50%-25% should be a combination of mulch, compost or anything that is light and airy in nature.

I suspect from your photo's that you have used either garden soil or bag soil. This holds a lot of moisture and does not hold any air which will hamper your plantÂs ability to absorb nutrients as well as cause root rot.

I would carefully remove the plants with as many of their roots as possible. Then remove half or more of the soil, replace with pro mix potting soil, mix it all together then replant your plants.

Once this is done, watch your watering until they take hold again and start a fertilizer routine every two weeks with either the blue stuff or organic fertilizer, which ever you prefer.
