3rd week of flowering, top leaves curling and dry..

Here is a pic of my Jack Herrer going into the 4th week of flower, she was underfed for about 4 to 5 days and I just completed a res change, just wondering if she looks permanently damaged. Any expert opinion? All help appreciated!



Now, Im not sure exactly what I can do to promote regeneration from the plant, but I am hoping one of you expert growers might be able to kick me down with some knowledge
Thanks again!

the leaf curl suggests she was overfed.

And a few pics of my other girls for you guys to check out; but these are fine (dj shorts blueberry is a VERY versatile strain).



this little sucker is going to be mighty fine smoke

and here's a shot of the room from the door... having space issues now and I am kinda lost as to how to adjust the room around to help the light get around. As you can see I have a t5 light underneath the 3. Any ideas guys?

Overfed? Hadn't even thought of that; would the other leaves be showing signs too? Last post i had a pic attached with the AC in back ground, thats the same plant but 2 diff stalks, as you can tell the ones more centered under the light are the most effected. What can I do to adjust for this? running bubbleponics.

any other opinions?
