That's pretty normal, mine do the same. It's the lower fans leaves, correct? They die off as the plants matures, whether to old age, lack of light, etc....and should be nothing to worry about, as long as the rest of the plant looks fine. It's probably due to the plant burning up nitrogen, during the stretching phase. You should be just fine. :)

Agree man you'll be fine. Check PH runoff and move to more p for the flowering. 1 gal grow bag seems small. Always hear 1 gal for every 1 foot but hey I grow hydro so no worries on root balling:blsmoke:

Ooops, I didn't even look at the first pic.lol Yeah man, it looks pretty good. MH works well for flowering, growers have used them for years. HPS has a slight edge, but I don't think it's all that big. Your's looks fine. It does look to be going a little nitrogen deficient, but as long as you keep some in the diet, it should be okay. It might yellow a little earlier than optimum, but at any rate, it's far enough along, that you'll still have a nice harvest. Well done.:leaf:
