Buds not filling out

Having problem with my ebb n flo garden.... I have 9 plants that are using general hydroponics 3 part formula, everything was great up untill the last 2 weeks of flowering. It first started with the stems turning red, and the buds haven't filled out at all. The older leaves have turned purple now and i know i have a phosphorus Def. Do you think if I flush my plants now and put full strenght nutes in the rez do you think the buds will start to fill out. As today is day 52. Im growing Sweet tooth#3, and its a 55-60day strain. Whats ya'll thoughs? Is it just a waste to add nutes agian? My yeild is greatly affected.

I wouldn't do that. You will almost definately cause an overfert problem. Not too mention your buds will be jam packed full of nutes. Your plants are nearing the end of their life cycle and look for certain things to sustain its life a certain points. The need for N-P-K has dwindled. If you do FLUSH, then ram a bunch of 3part into it, it will amost certainly lock up once it starts taking in the food, and will then take forever to dry out.
What did you feed them besides the 3-part? any bloom enhancer? Mag. supplied by? carbs?
At day 52 of a 55-60 day life cycle you won't get much more weight on their. THC will just start to degrade.
Goood luck!

nope do not bother giving them loads of ferts, you will burn them before they are ready and it will need a propper good cure to loose the harshness.
your buds will not fill out in 5days anyway and even tho the pack says 55-60days, its usually rubbish and theyre nearer 75days, more if u counted flower from first day of 12/12

No, if you are harvesting within the next week, using ferts now will cause you to wait to harvest at least another week longer, you don't want ferts in the plant before you harvest,

the purple leaves sounds like it's a color changer and it brought out it's colors towards the end of flowering.

The buds always stop growing near harvest, it's just the way the plants are, the buds grow the best towards the middle of flowering when they put on all there weight.

Are your temps cold at night? cold temps can trigger the color changing of the strains.
So the last thing you do want is to give it food, right now you should only have plain h202 in your res, NO nutrients what so ever, just plain water for about a week.
 
Thanks for the replies. Ok I know they purple veins is def. not normal. My night temps are not too low to cause colors to change. I know is a Phos. def. due to the leaves becoming so brittle. This is not my first ST#3 harvest so I know it should yeild way better. My guess is that im am f'ed with this grow.

Colors come out around 70-60 F not always, strain has to have the gene, sometimes the strains will show color on there own without any intervention.
Yes, they even get purple veins dude, you got a pic of it? I am telling you sounds like nothing wrong with your plant, but you sound like you got a case of the "worries" :)

If your temps are low and cold, your yield will suck and unless you have grown from clone you will not get the same yield as you did before, with each seed you grow, even though it's the same strain, you will most likely get a different pheno, and when you do you will get a different yield.

you didnt like my answer in your thread in the hydro section??

i was sugesting you get some B-cuzz flavor and add some.
dont end your grow if there not done. you WILL regret it. atleast when your smokeing them and you dont get anything.
fix the def, let them recover and extend it a few weeks untill there ready.

nar rubbish, the leaves are brittle because the plants nearly finished. ive had some with purple stems, purple veins, purple under the leaves, purple calyxs and the nighttime temps are doing some of that.
but like i said before i bet you have the flower ttimes wrong (you didnt even reply to my post!!) and i bet you still have a tonne of white hairs and more and more still coming.

@digital hippy, dont be telling people to add shit to flavour the buds....
 
Smokey - The hairs on the buds have all turned orange and there isnt any new hairs comming out, doesnt look like there is any new growth what so ever. I've grown this strain b4 so i know what kind of buds to expect and these are no where near what they should be. Its like they started to grow but then stop'd after about 3-4 weeks. I was waiting for them to explode but they just never filled out. Theres alot of main stalk where the buds should be forming together, and they're just completely pre-mature looking. I want to take pictures to show you but after OG got taken down im sketchy on putting pics on the internet now. I added nutes and im at day 54 now, im gonna wait a few more days to see if things maybe pick up... If not then im gonna go ahead and chop. Im gonna be real dissapointed if they dont start filling out, they look pitiful.

Chances are around week 3-4 you overfed or locked out nutrients somehow - possibly fluctuating PH, hard to say. Obviously the damage has been done.
As for purple veins - on the stalk? this is 100% normal on many strains of cannabis.

You should be going by what the plant is telling you not what the seed packet says.

When bringing a young plant up to full strengh nutes you need to read the ppm's daily. If they are taking water and leaving nutrients in the reservoir (ie, the ppm's rise) then they require less nutrients. If the ppm's drop then they require more.

When a plant is finishing late in flower their nutrient intake rapidly declines. When this happens and your reservoir stabalises around 500ppm - 400ppm the plant has almost finished and it's time to flush.

Red hairs mean nothing, I grown a strain that looks complete and finished at 42 days 12/12 but it's not ready until 65 - 70days.

just when a plant looks ready, more hairs will grow. while it will get you high at 54days, its not so much of a stone. 8 weeks = 64 days and even then when ive done them they dont seem ready and i found them better at 75days.
i also hope your counting flower time from ~2 weeks after flipping the lights to 12/12, otherwise you need to add on another 2 weeks to the total flowering time.

kabbage said it. some where along the flowring period you over ferted or there was terrible ph flux or both .

do you know even in a hydro setup you really should not go abouve 1.2 -1.4 ec max even lower than that will do good.

bottles just try to get you to use nutes up quicker so you buy more, dosnt matter which company they are made by, they ALL do it. when i use to ebb and flow with rockwool and also i did drain to waste in rockwool too

in the ebb i never went above 1.2 in flower and never higher than 1.0 in veg. my first time i wasnt so conservative and use acording to the bottle and i didnt realize the bottles recomendations when mixed gave me like 2.3 ec and my buds on that run were exaclty as yours are. they are there and smell and the hairs look mature and so do the resin heads, but you can practically see thru them and when they dry even the bigest ones are only a couple of grams. it is because of to heavy of feeding consistantly through the 12/12 cycle.

shit in my rockwool drain to waste i ran .9 ec all the way till the last couple of weeks and would take it down to .5-.7 ec.

hydro can be very unforgiving and thats why ive been focusing my attention to mastering soil organics and all non active hydro systems except for maybe a top feed drip onto pro mix or soil.

also rockwool is nuetral and you dont have to run 5.5 ph with it if you clean it out properly before you use it. i used to soak and drain and flush my rockwool over a 3 day period and by doing that i ran my ph at 6 with a drain to waste. rockwool is neutral when all the residuall lime gets flushed out and once it does it dose not affect ph in any way what so ever the reason why the ph goes up then is because of the way the plant uses nutes and grows..

never soad rockwool lower than 5.5 if so you will fuck it up and battle with ph the whole grow.

soak 24 hours at 5.5 ph then flush each 4' cube with like a pint or 2 of ro water and then soak again in 5.5 ph for 24 hours and then flush with ro really good at least a quarts per cube and then flush with whatever nutrient you use at around 5.9-6.1 whola!! no high alkaline rockwool to combat with.

sory for jackin this thread and going off topic,, if i even did......hmmm

It's nice to see someone else growing the Sweet tooth - it's such a wonderful smoke. A friend of mine that I gave a few buds to told me it was really top notch and I can only agree (Don't have much experience with anything other than what I've grown myself so I can't really compare). But a nice and sweet taste with a little hashy harshness. Are you also growing the weekend specials "inspected from bulk" from seedbay? Some people have been saying they might be seconds. Please show us some pics if possible.
Well I just harvested my first crop of Swt #3 last month, and I had the exact same problems you did. I'm thinking the purple veins is a strain trait though - my plants had that and also some coloring of top buds and leaves. Some other people's swt #3 pics I've seen showed a lot of coloring. I was overferting too - just blindly following the directions from BioBizz, and some plants showed signs of overferting (clawing). When looking back through my pictures I can see that everything looked fine until somewhere between day 21 and 31 - the leaves became brittle and started pointing upwards:

Day 21:


Day 31:


My yield pretty much sucked - a little more than 300 grams from a 600W light, and swt #3 isn't supposed to be a bad yielder. I did have other issues too tho - thrips were pretty aggressive and in the beginning the intake air was too cold - the pots felt very cold to the touch. Also I think my clones weren't developed enough before I switched to flower because they kinda went into a panicked stretch ending up mostly hollow stems and little bud.
When I've seen other people's budshots I can see colas rising above the canopy - mine were pretty much just hiding in a big mass of leaves - is that how yours look too?
