It is hard to say what all could be up but it might be as simple as a lack of light to the lower leaves since, at least now, the rest of the plants look very healthy.

Your lighting isn’t exactly high powered and from the pictures the lights at least appear to be rather high for fluorescent lighting, not nearly as close to the plants as many people keep that type of lighting, or again it at least does not appear to be close in the pictures.

The reason I think it might possibly be lighting is I once popped some beans and they were much slower to pop than usual so I started some more in case the first were not viable any longer and then they all ended up popping. They were all the same type of beans from the same place and all grown the same except for lighting in that I did not have enough room inside for them all and put some outside in large pots on my deck.

The ones inside were under low wattage lighting, a 150 watt MH for veg and later a 150 watt HPS for flower. The lower leaves on the indoors ones got brownish spots and turned yellow and dried up and died off but the plants of the same type give the same treatment in the same type of soil they grew under the natural sun were lush to the bottom until near the very end of flowering when it is natural for lower leaves to die off. There was no difference between the indoors and outdoors plants other than the lighting so all I could figure was a lack of light penetration indoors.

That may not be your case but when something similar in appearance happened to me that was all I could conclude it could have been from since lighting was the only difference between the different plants.

I am curious about one thing, what sort of reflective material is that on your walls?

I would double check the PH again and also get that light closer it a cfl get as close as posible without burning the leaves.

twice a day???? what is a normal dose?? not gonna dig out the bottle to find out:bigjoint:...

seems excessive, but from looking at your plants (at first at least) it looks to me like they want some more nitrogen
