nut deficiency or what?

I have been battling a nutrient deficiendy problem and it seems neverending. I have flushed, adjusted my PPMs to 1600 & adjusted my nutes formula. Here are some pics of the worst leaves. I suspect Nitrogen or Potassium but dont know how to fix this. PLEASE HELP!!

1600 ppm is way too high... the highest it is ever supposed to go is 1330 and its only for a week and goes down drastically after that... what brand are you using and are you following their feeding regiment?

I am growing white widow in a bubble system and am supplementing w CO2. We're running 2 1000 watt lights at about 18 inches from the plant. the feeding schedule is as follows: we feed once a week.

Micro 7.5 ml/gal
Bloom 15/gal
Liquid Karma 5ml/gal
Sweet 10ml/gal
Silica 5ml/gal
thinking of adding Koolbloom or Hydroplex 5ml/gal

it also looks like it could be a phosphorus deficiency effecting your plants...

how can i supplement phosphorous?

yea when you put all that together, it adds up to be a bit too much my friend... you need to do some real research on nutrients. i recommend deep water culture hydroponics, but that may be what your referring to as bubble system. try canna nutrients. aqua vega and aqua flora. their feeding regiments are technically and scientifically developed around marijuana.

by using a canna product called PK 13/14

you can find it here http://www.hydroasis.com/hy/productdetail.aspx?id=1056&product=pk-13-14

i have already lowered my nutes and done TONS of re-search..there is so much out there tho that its hard to get thru it all...as for the deep water culture that is exacltly what we're doing...its my second grow but i cant seem to get this nute deficiency under control...if it is a phosphorous deficiency what can i add to the plants??

my wife says i have a nut deficiency... lol

Thank you. I think the thing is with his situation is that 1600ppm, assuming he's talking about the 442 scale (.7 conversion), it pretty darn high. Some people with some strains given an optimal environment may be able to pull off 1600 but most of us can't. Given the fact that he's using the GH 3part with a few additives, I'd say to cut back to 1000-1100 ppm. I wouldn't recommend more products at this point since he's using too much of the products he already owns.

nut burn < toooo many nuts > like mentioned, 1100 at the most

Most likely lockout due to too high ppm/out of balance solution. Picture 1 looks like Mg def and maybe some other micros. Does new growth have a little bit of a yellow hue? Picture 2 & 3 are Phosphorous def.
You say you feed once a week, in DWC? Does that mean you change the solution, add more nutes? I don't get it. Can you clarify?
I think your problem may lie in the answer to this question.
