This is day 31. Im not sure what the problem is here the very bottom 2 leaves look like their dying you cant see them in the picture but i dont know whats causing the yellow outline on the leaves. I havent used any nutes ive been watering daily only so the soil is damp and so a little leaks out the bottom of the cup. Please help me out? Will she be ok?
