its harder to tell under the HPS lighting, but i'd say nute burn for sure. Take them to the bathroom and flush those plants out with plain PH'd water till you see a good amount of run off. When the color of the run off goes from ? to clear....they're okay. or you could try increased watering like gradual flushing...but i don't guarantee that working, probably won't in your case.
And you might have magnesium defficiency, can't tell. Try some epsom salts.

Can you get a shot with the HPS off after lights out using the flash on your camera? And maybe use this form to help us help you From here it looks like a classic Potassium(K) deficiency. Either way it looks like you are pretty far along into flower to be of much help now. Maybe for the next round tho? Here's some info:
Potassium (K) Mobile Element and Macro Element
Potassium plays a big role as well. Having good amounts of potassium in your plants helps in having sturdy and thick stems, disease-resistance, water respiration, as well aids in photosynthesis. Potassium is also found in the whole plant. It is necessary for all activities having to do with water transportation. Potassium is necessary for all stages of growth, especially important in the development of Buds.
Having to little of Potassium in your plants causes the plants leaves to show retarded growth and show a scorched tip and edges around the leaves. Plants may stretch and your branches can be easily broken or weak. Don’t get this deficiency confused with iron, because it almost acts like iron but to tell the difference in the two is: for potassium the tips of the leaves curl and the edges burn and die. Older leaves may show a red color and leaves could curl upwards. Dead patches (Necrosis) can happen on the margins of larger fan leaves thus, the leaves will eventually die off and turn brown. The Older leaves will show different patches of color (mottle) and turn yellow between the veins, following by whole leaves that turn dark yellow and die. The plants overall growth slows down, mostly when they are in vegetative stage. To little amount of potassium also slows the growth of buds during flowering stages. Dark edges will appear around the edges of the leaf when the deficiency is starting to happen. When your Relative humidity is low, you can almost bet your going to soon get a potassium deficiency from your plants perspiration.
Potassium can get poorly absorbed when having too much Calcium or ammonium nitrogen, and maybe cold weather. Having to much sodium (Na) causes potassium to be displaced. SO keep those in mind… Parts affected by a Potassium Deficiency are: older leaves and leaf margins.
When you have too much Potassium in your soil, it can lead to big troubles, like salt damage and acid fixation of the root system, as well as too much potassium can cause a calcium deficiency. Your fan leaves will show like a light to a dark yellow to whitish color in between the veins. Due to a molecular imbalance, potassium toxicity can cause a reduced uptake and lead to the deficiencies of Mg, and in some cases, Ca. Also leads to the other nutrients to not be absorbed properly leading to lots of other deficiency such as: magnesium, manganese, zinc and iron and can cause problems with calcium as well.
Hope this helps.
Peace

Yeah, looks like a K def to me also...try running a little DynaGro Pro-Tekt in there - just make sure to watch the PH since it's pretty alkaline.

Interesting case...
I run dynagrow... and its hard to burn the plants with the stuff....
I do also agree with the potassium def....
But whats interesting is this is a fairly common thing....
and its one of the circumstances where flushing will further leach potassium from the soil and the plants will be more damaged...
One thing Ive noticed about some K def cases like this.....
is some of the folks who get it are probably underfeeding their plants.....
I happen to like dynagrow... it works for me....
The protekt would be a good thing but it looks like you are pretty far along and you really dont need to go thru extraordinary efforts....
Your leaves may not look pristene but I think largely your buds will be uneffected....
I would keep this in mind for next grow.... and make sure that you add considerably to available potassium next time around.... or simply feed the plants more....

Ill try and get some snaps when the lights off as well.
Well, it cant be a mag def, I add calmag....
My mix is,
4 gallons, 4tsp's dynagrow bloom, 2tsps calmag, 1 tsp PH up
This gives me around 450ppm using a cheep 40$ ppm meter. With a proper PH.
Flushing isnt gonna work for me, it cant be nute burn really. I usta run the same strain at 800ppm w/ the same meter, same food....
Ill check out that dynagro-protek. That looks like it may be viable for the next time around....ive got 2 ladies getting ready to go in.
Problem is I run on cycles, so when you look at it, the plants to the direct light are almost 8 weeks, the plants to the left are about 5and a half weeks.
I JUST did a flush of their systems...and its hydro folks =)

Oh its hydro..... lol... <<grins>>
I was reading your response and you feed the same way I do.... 1 tsp gallon.....
and I never get defs....
Yup I would say the protek is the correct approach....

I agree with brothermonk and MTF. K def... I think 400ppm for hydro is very low imho. Did you get burn when you ran 800?? I am pretty sure you can go higher unless your meter isnt telling the truth. Maybe you should invest in a better meter.
Is it calmag plus with added Nitrogen?? With 2 tsp a gal you have added to a total of about twice the amount of K as of calcium so that will def give a K def. I think you need to add three times the ppm of K. I checked your ppm in a nute calc and if your % of Dynagrow liquid bloom is 3-12-6 and its calmagplus your numbers are N-93 P-69 K-66 cal-111 Mg-39 Mel Franks targets for cannabis in bloom are N-100 P100 K 200 Mg 60-70. Not saying this has to be reached to grow the weed, but it does show that you are definitely getting way too much calcium compared to K. Hopefully the new addition fixes the problem.
Well I must be bored .... If you add the reccomended amount suggested on label .5 to 1 tsp per gal of Protekt which has 3.7% K you will add an additional 20-40ppm of K, Just remember this will make your Ph rise so adjust after addition. I still think you may get a K def with only that amount. and I dont think you should add any more then suggested. Good Luck.
