Im afraid im going to lose one of my plants. It started lightly browning the other day at the top of the plant and spread. I have no idea what happened and why? What can I do to bring her back to health if possible. Also my other plants are starting to slowly yellow from the bottem up. Please check my other thread post ( http://forum.grasscity.com/sick-plants-problems/540008-new-grower-they-ok.html ) and look at my plants thank you so much!
