Do I need more micro nutrients???

So I have this problem. I have some plants that are yellowing and curling. I thought this was a cal-mag issue so i went and bought some. I have been giving it to my plants for over a week but I still have not seen any changes in my plants. I was told to use AN Revive. Is this a good product? Or should i stay away from this? Please help guys I don't want to lose my crop.

fill out the troubleshooting form. Stop the cal/mag as it can cause yellowing. Do not know that product. There is a soil troublesheet in my sig. Copy and paste to thread and answer the questions.
