Harvest a Pound Every Three Weeks!

DIRTHAWKER said:

Im at 5 weeks with one of my racks and the DAM!! yellowing has started again.

I know its not a heat problem beacuse the highest the temps in the room gets is 87. An its mostly not yellowing at the top near the lights, but low random leaves.
I think it may be an over fert problem?

Stink? or lion? or any of yall? In my journal and earlier pics ( before i started using RO water and c02) the plants stayed green all the way to the flush.

My thinking and i may be wrong but when using my 600ppm tap water i would bring the ppm to 2000ppm in the flower res. And the plants didnt yellow.

Maybe beacuse im bringing the ppm to 2000ppm with clean 0ppm water its too much?????
and the leaves are getting an overload and cant hold that much nutes?

I am flushing with clean water for 24 hours in this rack and need some input on what to do with the nutes afterward?

Yo Dirt - yes, you are right... with 600ppm tap, you were running the equivalent of 1400ppm with 0 ppm water... so you are running 600ppm hotter than you were with tap! Botanicare recommends lowering your ppm's around week 6 (as do most nutrient makers).

What up with these yellow leaves? What are your res temps? I wonder if you tried increasing the irrigation interval to 6 off 1 on... I wonder if the roots start to slow down the drainage rate as they get big at weeks 5 - 6 and cause a drop in the amount of available oxygen? ...or perhaps they need more frequent watering? haha - I am really reaching here!

Not sure we have the same issue - as my lower leaves were unaffected...?

just finished building my second stink unit


i use 35 gallon totes with prlly only 20-25 gal in em

and i got the ranch fence post its a little bigger ......

other than that its same

well here is the pic of it

Nice! Looks great. The bigger res will come in handy!

Ok stink and gang... I manged to get al the way to harvest time without bothering you guys along the way and realley diving in to the thread. I really appreciate the community like spirit in info sharing and I am very gratefull. COuld you guys take a look at my albulm link below. I am very concerned that my buds arennot compact enough at all and just plain underdeveloped. Any sueggestions would be most hlpefull. STrain is mazzar and and this is week 7 12-12 using stinks to the t instructions and res is flushed right now

Way to go! Genetics plays a big role in bud formation. This strain looks like it needs more time and more light - though it may never be the big, dense bud you want. If you don't see considerable bulking in another 2 weeks, you may want to cut your losses and get some other genetics. If the show really starts to look good in 2 weeks, you may have a winner on your hands in the form of a long maturing sativa - 12+ weeks is possible! Certain varietals will never complete indoors.

I have a newbie question. I have been using a drip system for veg. and ebb n flood for flowering. both are easy to take the tops off and check PPM and PH. I just started a week ago transforming over to stinks system. I have a Veg. unit built and running so far. Built to stink's specs, I only have a 2" hole in the rez to check everything. As long as the water level is right then all is well with checking. But if I add PH up or down (and soon will be adding nutes) there is not a easy way to stir the mixture. Everything stays in the corner where the hole is for a while. Is there a way to get everything stirred quicker so I can get my measurements without turning off the pump and seperating the two totes so I can move along with my schedule quicker?

Yeah - this is one issue with the system that I notice too... I handle it in true stoner style. I check the PH once or twice during the 3 weeks max they veg - and then just add water or week nute solution with the PH adjusted to compensate as best I can - forget actually adding PH up or down to the res directly! haha - I know, not the scientific approach we are seeking - but if you fill the veg res as much as you reasonably can, it is usually good to go with just a weekly topping for the 10 - 20 days we veg. Just look at the plants. If they look OK - don't trip to much on adjusting your res daily.

While PH is important - it is normal for it to change and there is some leeway to the perfect 5.8.

OMFG.... I just got done with my first harvest. 9 hours of trimming later and holy crap.

I went and purchased a 50gal Rubbermaid container to make into my drying chamber and I ended up with WAY too much bud. To those of you just starting up, do yourself a favor and remove/trim those lower branches. I ended up with a crapload of popcorn buds which just ended up in the trim pile. I had more than enough in medium to large-ish colas/nugs to fill my drying container... in fact, I had to get rather creative so I could stuff more in while hopefully avoiding mold issues.

In the end, thank you so very much SB for sharing your knowledge with the rest of us. This is 10 bajillion times better than my previous attempt at a soil grow.

Now I think I need to find some more space somewhere to cure all this...

add one air stone. That will mix it well.

Thanks fishenfool. That sounds like a good idea. I will give it a tryl.

Thanks for all the help stinkbuds! I flushed the rack for 24 hours, cleaned and then brought the ppms to 1400. then dialed in the ph. I will let you all know how it turns out. I must say im really looking forward to what yields from my 10 bubba kush rack. The one bubba kush plant i harvested a couple weeks ago was a massive yielder at 6.8 ounces.. now if they all yield anywhere close to that one, i will have close to a 3lb harvest.. holy cow that would be nice!! too bad they are such slow rooters.

ok, in original regular ol' nft there are no timers and sprayers. now noone will argue that stinks system isnt wonderfull. and the timer was the cure all for me personally in my cloner. but i'm wondering if anyone has done the sprayers inside the runs like stink does but without the timer......just 24/7 ? if the soup is oxygenated enough it should be astounding growth. any thoughts? or has anyone done this and if so ....how'd it go?

yea i gave my input in other thread too bugs ...but yea i forgot to say i only ran it 24/7 for about a week .......after that week i got timer ....but they had already started to develope nice white healthy roots out of the rockwool that were dropped in the 2 inch net cup

no probs with rockwool this i think is cause i had a bit of a root tail on em when i put em into bloom they were not freshly rooted ......they had developed that root tail

i just changed whole system over tho bugs and will try one with constant on ....if within two or three weeks if it is significant i can let youknow by then

the only thing that worries me about that is the pump getting warm from running constantly, and making the res too hot.. thus having to buy a chiller which runs hundreds of dollars, or a $80 timer..


Chef

yea that might happen for sure good observation .....i run my room no co2 and no airstones in rez whatsoever ..the waterfall works well im sure for oxygenation ....but yea i wonder if that might run temps high ........im gonna test this out for the first two or three weeks of bloom ......

i will put a floating thermometer in ther and check daily for more accurate log of what happens vs. my timed ones

....i keep my room at the normal 74 degrees .......i have battled spidermites and they dont like it cool

lol they go crazy daisy when its like 85 or more degrees .....major multiplying

so whats the budget way of keeping rez temps in check?

Yeah that was my question too a few posts back. If we're rockin' 83-85 room temps with the CO2, what keeps the res from getting up there? Had some root rot happening in one post, i think from the high [78-79] res temps.

I lowered room temp a touch but that costs extra air conditioning.

I'm going to freeze some 2 liter bottles of water and swap out one per res every day.

Also bought a roll of 24" refleticx to cover the res and lid. The black res lids can't be helping the cause either.

Also bought some 6" ducting insulation to cover the light exhaust. That should help cool the room temp a touch.

So I'm hoping that between lower room temp, frozen bottles, reflectix, and adding daily tap water maybe i can get it back below 75f. If not... then we find something else to work on.

I think I read in the Cervantes' book res temp 65-75. Cooler water carries more O2.

check out this idea boys and girls ......use phed ice cubes or plastic big gulp cups filled with phed water ...then add them at diff intervals during day ........maybe set a timer ......its that or buy an expensive ass water chiller ...

Ok. Question
I've just harvested my 3 rd aero unit
is it normal for all of the plants to end up different sizes and different weights. Ie. Some of them r monsters and some of them are wimps
same strains and same batch of clones
I think I'll end up with over 10 oz from 1/2. Of a 600 hps or 300 hps which will b over a gram per watt
final weight on saturday
thankx stink. Never got over .4 grams /watt before aero + co2

man i am loving this new system and hope to accomplish more than my usual .4 g per watt ......that is what i have been doin and it has been so much work with trays ...

now i have 2 built and parts for 2 more so 4 stinkbud units under 2 1000 watt aircooled hoods ....

i also have that diff size thing goin on .... i think it is all about fine tuning everything .....i am actually gonna try a transplant of some to another system cause of such rapid growth i cannot believe it .....i have done this long enought to recognize when a plant is gonna blow up with weight by about week 3 of bloom so i can tell this system is very nice

Well right now I am basically adding ice cubes twice a day to keep temps down. I did the water bottle and it did help, but having to take it out, freeze it and put it back is too much of a hassle. This is kinda good because they need water daily anyhow. Someone has got to have found a trick to this by now

Q: What is the ideal water temperature?
A: Between 68° and 72° F.

Andyman made a water level tube for the Veg rez. I think you could make the tube a little shorter so you could add nutes & ph directly to the H2O with a syringe and some air line tubing. Or just run some air line tubing thru the lid too

a while back i had a post about takin a mini-fridge apart and using it as a water chiller. it works awesome, i just took all the outter shell and insulation off the parts, the compresser and all the lines stayed together i never had to disconnect anything. i find these mini fridges all over the place for next to nothing. it sure beats frozen 2 liters that only last a few hours, they thaw out faster than you can freeze another one, not a very good idea.

yea that fridge idea sounds cool but possible dangerous if someone dint know what they were doin

fukin sweet idea tho

i like the icecube thing ..although it prolly would get old having to freeze em all the time

i thought maybe like using super big gulp cups ...and then when they come out of the freezer just run a bit of hot water on sides so it will slip out into rez

lol u think about it tho and even that would prove to be a hassle
