Have you fed them at all since they were transplanted? A nitrogen deficient plant will often start yellowing at the bottom fan leaves and gradually work it's way up as the lower leaves die off. If nothing's being locked out due to pH, I'd still venture a guess that the plants aren't getting enough nitrogen. If you've been feeding it with a nitrogen-rich fertilizer, however, you should fill out the Troubleshooting Form so that we can get a better idea of what might be causing it.

If you haven't started feeding it yet, you need to start now. Start at about 1/4 the recommended strength and gradually work your way up until the yellowing stops.
Mr. Clandestine Reviewed by Mr. Clandestine on . ok...here we go again... So these ladies are about a month old now, and were just put back under a 400w mh after being under shop lights for a couple a weeks due to a broken ballast. All is well with the lighting...but now this!!! I've read it could be due to a nitrogen deficiency, or ph problems. But I need some advice. My soil ph is pretty close to 7 and the plants were just transplanted into an organic peat free potting soil. Here's some pics. PLEASE HELP Rating: 5
