lower leaves turning purple-brown
sorry for the confusion, i meant that im on the 6th week of flowering (8th week total, including veg.) and im not sure if i should redo the 5th week feeding first (that i missed due to last events) or continue to 6th week feeding scheduale.
i like it when the plants are filled with water and all leaves are pointing upwards, seems like they have an erection :)

Your 3 year old nutrients are likely no good any more. Plus, 6 different bottles? What the hell are you doing to those poor girls...? Most of what cannabis needs can be found in a (fresh) 2-part or 3-part nutrient system. Additives should not be used until there is a need for them, and until you have the ability to understand why you are giving the additive(s) in the first place. Is you potting mix 3 years old as well...?

Not unless you're in a pre-fertilized soil. (Miracle Grow or similar)
For most major nutrient systems, they have a weekly feeding schedule available on their web site. You are currently giving too much nutrients in a pot that's too small for the root structure. If you are following bottle directions, be aware that some companies label bottles as a stand-alone product. (they assume you only use that bottle on your plants) This can easily lead to overfertilizing. When in doubt, go with the online instructions.
Feeding in soil is best done (IMHO) once or twice a week (following a weekly schedule) with plain, properly ph'd water inbetween if necessary.

Test strips offer the same, cheap method of checking ingoing ph for clear water. (any tinting will skew the color-coded result...even with test strips) A ph pen would let you test runoff.
Looks to me like (if your ingoing ph numbers are correct) that either the nutrients are dropping the ingoing ph too low, or the soil ph is a tad low to begin with. (the 'claw' showing on a few of your leaves) and you are seriously overfertilizing her. I'd flush well, transplant to a larger pot, and at the very least cut-back to your base nutrients for flower. Every other additive you are using is overkill, and you are doing more damage by not knowing how to use 'em.
You should also think seriously about purchasing some fresh product, and do not fall for the marketing hype. Grow with the basics till you know how to troubleshoot the damage you're likely to encounter as a result of overdoing it.
Are you using any side-lighting? Just curious...

hey Rusty, thanks for your insights
im aware that the roots might become a bit tight, however i rather not move them now unless its really a must, also, in the first time (3 years ago) they seemed to manage well with the same container size, and the plants then were actualy much taller.
regarding the food i use - before starting i checked with two different grow shops and they both told me that as long as the product smells normal and not showing any signs of fermentation - then its "good to go".
the reason i use 6 different bottles is because that was what they sold me at my "first round", when i bought all the equipment, it might be too much, but it seems to me that it's according to the bio-bizz chart, and also the last time i grew i did it all according to the chart and had no overfertelizing problems, or any other problems.
after flushing the plants yesterday and checking the runout it seems as they were actualy not too acidic, but infact a bit basic compared to the desired pH (runout tested about pH 6.9)
and no, i dont use any sidelightings
all & all - my goal is to reach a successful harvest and if each plant will yield me as much 50 grams of dry product i'll be happy and very satisfied, since that will last my for the next whole year. i used to smoke like a pig and 100 grams would be gone in a couple of months, but nowdays i use much less and thanks to my beloved DBV i dont even smoke anymore. so im not trying to maximize the harvest quantity, and though i do apreciate the quality,i rather not spend any more money at the moment and also not make any big changes that im not 100% sure about.

now regarding some other stuff you wrote (Rusty Trichome):
i do have a problem of "the claw", small leaves all over the plant are curled inwards and appear to be in dark green. after searching this issue it seems that there are many possible causes for this problem, and not one simple explanation - other than that, the plants look healthy, the discoloration of the large fan leaves stopped for now, and buds are still swelling. so if i'll assume it is a problem of over fertilization and i want to cut down on the nutrients, how do i choose which one to lower?
last time i fed them it was according to the followings:
bio-heaven 4ml/L
bio-grow 4ml/L
alg-a-mic 3ml/L
bio-bloom 3ml/L
top-max 1ml/L
biobizz dont specify the inrgredients in their site, so i'll go over the bottles and specify it myself:
bio-heaven: N (0.91), P (0.18), K (0.24), Ca (0.28), Mg (0.20), Fe (0.017), Mn (0.001), Zn (0.002), B (0.018), Cu (0.0001), Mo (0.0001) - (i donno if these numbers are percentage or what).
biogrow: N (8%) - (of which half is NH4 and half is NO3), P in the form of P2O5 (2%), K in the form of K2O (6%)
alg-a-mic: N (0.1%), P2O5 (0.1%), K2O (0.1%), Ca (0.2%), Mg (0.1%)
topmax: N (0.1%), P2O5 (0.01%), K2O (0.1%) and also trace amounts of Fe,Mn,Zn,B,Cu
biobloom: N (2.0%) of which NH4 (0.9%) and NO3 (1.1%), P2O5 (6%), K2O (3.5%)
i guess in each bottle there are more ingredients that are not specified otherwise what's the point in making all these differnt products if most of them are used in the same time anyway (according to the chart)?
Soooo... any ideas what should i do next, which ones to cut down?
also, if one flush wasn't enought, should i flush again soon or should i first feed for a couple of times and only then flush?

and here's the chart im using:
http://www.growing-life.com/shop/biobizz_grow_chart.jpg
note that im using light mix and should be at the end of the 7th week (overall) - thought i haven't even started it due to current events and the flush.

Hmm...Did you read any of my post...?
Old nutrients (chemical salts) tend to bind together over extended periods. This can easily create a toxic condition in your soil.
A couple of the additives you listed are redundant to the base nutrients (and each other) and are likely contributing to the stress. I understand you are following online directions...but I personally shy away from nutrient companies that recommend you throw every friggin thing under the sun at 'em and keep your fingers crossed. Advanced nutrients is another of the same ilk. But regardless...if your nutrients and additives are spoiled, it doesn't really matter what additives you use. They're all toxic.
Were I forced to go Bio, I'd stick with the Bio grow, Bio Bloom, and perhaps a bottle of unsulphured molasses to replace Top Max. IMHO, the Alga grow and the Bio Heaven are unnecessary. But if forced to take one...I'd go with the Heaven.
And if you are unable or unwilling to transplant, there's not much more I can add. Roots can not feed off of each other, and there is likely not enough soil left in the pot to properly feed and hydrate em.
Flush well, transplant, and go get some fresh nutrients.

Sigh, there are just some that won't listen to good advice, goes right over the top of their heads.
Monkey - Rusty is about top dog on this kind of issue. He gave good info and you seem to not want to utilize it. The biggest problem your plants have is your reluctance to give them what they need
lower leaves turning purple-brown
sorry if i gave the impression that i wasn't listening, i did come here to learn.
anyway, i'll probably move them into 3 gallon pots soon, and i already flushed them once. regarding buying new fertilizers it's a bit more thricky, as im very short on money and where i live these things don't come cheap. i searched the subject of "biobizz shelf life" and for what it's worth, some people say that their products are still fine after 2-3 years, and others say that the product loses potency over time but don't become toxic, so i have a bit of a conflict here, since with all the respect i have to the info given by Rusty, i would really rather not throw away my fertilizers and buy new ones, unless i really must do it.
Rusty, i realize you are a much more expereinced grower than i am, but that doesn't mean i have to take your words for granted. and so when i encounter differences between what you claim and what i've witnessed such as that the runout pH was actualy higher rather than lower, and that you are the only one claiming the products becomes toxic (and that's including the salesmen which clearly have an intrest of selling me more product, and they still told me it's fine) and the fact that the same pots were already successful in growing helthy plants twice as large - i need to concider your advice with great caution - especialy if it's involving drastic measures.
at the end of the day, its my decision to make and i'll be the one dealiing with its consequences, and so i would apreciate not being confronted with emotional pressure such as "Hmm...Did you read any of my post...?" and "Sigh, there are just some that won't listen to good advice, goes right over the top of their heads." as it is clearly more ego related than professional.
with all that being said - i really apreciate your advices and the time you spent giving them, and i hope to continue and learn more from you, and from every other person who likes to share his knowledge on the subject.
peace!

If you can provide me a link to counter this statement of fact, feel free to post it. From what I have read, understood and experienced...2-3 years is pushing it and salt build-up creates a toxic soil enviornment. Perhaps you could Google the shelf life of liquid plant nutrients and see what pop's up.
And as far as acting the professional...We get paid nothing for sharing our experiences with others that are willing to learn, and I get paid the same if I chose to avoid those that either don't appreciate it or just want to argue.
I'm not known for my 'touchy-feely' embelishments in my postings. And since it displeases you to hear me try and help you over the rough spots unless I coddle your whiney butt and hold your hand in a touching 'kum-ba-yah' moment, feel free to take the other advise you were given and run with it. It's your garden, not mine.
You were given strong points to ponder. Perhaps you should go ponder 'em...:jointsmile:
But seriously...If this garden is for your meds, I wish you the best. :thumbsup:

Rusty, I think you are missing his financial issue, and as you know, some is better than none sometimes. He is aware of the risk, but is making his own choice based on financial constraints.
Yes our reward is other's success.
