Ditdotter: Thanks for the tip on the vinegar. I will try it this weekend. I already popped for the pH down but it won't arrive for several days. I will be posting results.
nevergetsold Reviewed by nevergetsold on . Leaves Curling and a Bit Leathery My first indoor grow and the 4 week old plant's leaves don't look good. The first few sets of leaves were turning yellow and brown. As soon as I had more leaves I removed the first ones.

Now the yellow/brown symptoms are gone but the leaves now are curling and look a bit leathery. Here is my questionnaire and I will add more photos in another post. I have been lurking on Rating: 5
