Just a few weeks ago she was looking great. First thing that showed was the leaves starting to wilt. Next, some of the tips look dry or burnt, then got some of the same in the middle of some of the leaves. Now there are some lighter green spots showing along the main vein of the leaves. I took a bunch of pics though couldn't seem to get a good one of the burnt spots.

She has been through a little trauma lately. We had some family move in with us due to economic issues so had to build a new grow closet rather quickly. So, the amount and direction of the light has fluctuated quite a bit lately.

Thanks for any help. Really appreciate it. This is our first grow.

Well the burn spots haven't increased and she seems to be getting better. However, I am still seeing the yellow spots on the larger fan leaves. Also the new growth all seems to be a very dark green. I have been watering with just plain water for about a week now. Any help would be greatly appreciated.

Miracle Grow All Purpose liquid directions are for a 10 day to 2 week period. Make sure you aren't overdosing 'em.

I much prefer a 18/6 veg schedule. So do my plants.

Transplant into a larger container, looking a little big for her shoe :thumbsup:

Thanks for the info. I was planning on transplanting tonight. I have let her dry out for a few days now so it should be pretty easy.
