Argh! cant get past this problem. any help would be great

[AOD2012]

hey everyone. so i am having some issues with my plants. first off, i am using promix w/ myco. adding perlite and EC, at 6 parts promix, 2 parts perlite, and 2 parts EC. no added dolomite lime. i am feeding using jmansweed's schedule. just hit the four week mark. the strain is sharksbreath, and i pick at just around 9 weeks.
i went away for a little, and i thought it was a magnesium def. and i treated with some GH CAMAG. when i got back, this is what everything is looking like. i dont know if it is an iron def, or a ph issue. my runoff is at like 6.3-6.5, and i am feeding at that. thanks for any help people. the first pics are the worst off, and the last two are ones that are not as bad. thanks a lot

Looks like fungus gnat or root aphid damage. If you see one or two flying around once in a while it may be much worse than you think. If you put some sticky cards down on the top of the soil there could be hundreds stuck on by the next day. If this is not your problem i'd really like to know as well. I had the same issue of going yellow big time at around week four.

Your going to get differing opinions here. My best guess is a lack of N that plant could be a N hog even though they dont need N in flower but they do need some it looks like the plant has suck all the N out of the plant. The fastest way to fix any deficiency is to foliar feed. That is not Mag Deficiency. Go get some Revive(1-0-0) and feed her with it. Your PH is fine. Thats what I would do.

Good Luck

Hungry or the light isn't coming on! Mix equal parts of grow with the bloom for a feeding or two. You may need to add some grow all the time. All plants are slightly different. I've seen one plant full of holes and all rusty looking from Ca problems...while others right next to it are healthy as can be.

yea im using earth juice products, and the bloom has no nitrogen at all. i feed with the grow throughout flowering. i guess i am going to have to up the N on this pheno. well im happy that it is most likely something simple like that. well, i ordered some revive, and ill give them a little extra does. i am am little less than halfway through with this one, so is it safe to add extra N at this stage of flowering? thanks a lot people.

yes when I have to do that I just soak as many leaves as I can I dont put any on the buds. The leaves will suck up the N. Keep in mind that most of those leaves wont recover. You need to look at new growth to see if there is improvement.
