Yellowing Leaf Margin

Discussion in 'Sick Plants and Problems' started by stoner224, Mar 26, 2016.

  1. Hi,
    I'm somewhat new to growing. I started my plants indoors and they all looked great until a week or so ago. I'm using miracle grow soil since I will be moving the plants outdoors in May ( Yes, I was a little to early in starting them) The problem is that the tips of the teeth on the leaf margin are turning yellow. It's not on every leaflet but maybe half. I just also noticed that the leaf tip on a few of the leaves is dried and brittle. You can touch it and it will break off. I only use fluorescent lights to grow and they are on an 18/6 cycle. The two strains that seem to be affected most are a Lemon Haze and a Lemon Skunk. My other strains all seem to be doing fine a couple lower yellow leaves but nothing like the Lemons. I don't use any nutes at all on them and they are not starving for water. Any advice would be great! IMG_8825.JPG IMG_8828.JPG IMG_8828.JPG
