Thanks Jgreen!! I just harvested and dried ... I got 15 ounces. One bubba kush plant yielded 6.8 ounces alone... Im looking forward to my newest batch that just went in...its all bubba kush...should be interesting.

sounds like a really good yielding strain
congrats

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.
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. maybe bringing the ppm to 2000ppm with clean 0ppm water is 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?

The leaves are curling under which tells me nutrient burn...

Lower the ppm's for sure.

I thought plants always turned yellow as they neared the end of their lives. My babies pretty much always looked perfect until the last 10 days or so then they looked like hell. They are just putting all the everything into resin production.

Not an expert, but when I moved, my tap water is 20-22ppm (yeah, I know!),compared to 220 from before - I had to adjust the levels of PPM and bring them down from where I was before, starting it around 1400ppm and adding nutes every day or so if the still looked perky and green - most of my strains now work best in the 1800-2200ppm range, as before I was able to go as high as 2500-2700 before seeing burn.
It's all about tuning it in =)

Im seriously thinking about running a batch with my tap water and adjust the ppm like i did before i started using RO water to see if the plants stay green. I think the yellowing is a combination of heat and nute burn. The buds look different lately since the yellowing..Kinda burnt and crunchy... they still taste great though. but i miss how they looked before..... I need to figure this out!

Hey im on week 43 days flowering and im getting the yellowing too... i have Nute burn and Heat problems. My ppm went up to 4k and my temp stays constant 84F with lights on.

Comparing our pictures im 99% sure you are having nute burn problems as well

Thanks for chiming in. Yea it has to be nute burn, ever since i started using RO water i have been burning certain strains. I think once they get burnt there is not much you can do. Ive since readjusted the ppms and in the future with these certain strains i think i know what the limits are.

Yeah, I made the same mistake with my SSH once I started using RO water. Didn't realise that with my 650 ppm tap water, 1,500 ppm's in my res means only 850 of that is nutrient's, other 650 is all the crap in tap water.

I used RO water with ppm's of like 50 or less, and went up to 1,500 ppm's again. Big mistake! That like doubled the nutrients the plants were used to, they burned so bad I thought the crop was a loss.

Just ran straight RO water for like 3 days till they started making white pistils again, then went low, like 900 ppm's. Worked like a charm, but the burned parts never seem to recover, plant gets kinda dryed out too. Spray some water on the leaves after lights out, or up the humidity a bit.

I ultimatly think it effected my total yeild because the plant growth completly stopped for like a whole week when it burned. Never really seemed the same after that

But still a great harvest! Good luck man

Hey Dirt,

Dope grow and thanks for contributing on this string and Stink's as well. I remember back on Stink's thread that you were having issues getting your cloner to stop leaking. I have the 18 gallon, roughneck. I've tried weatherstripping, plastic, you name it. What did you end up using to stop the leaks? If I put a decent amount of pressure on the top at the edge, it'll stop the leak... but that'd require all kinds of rigging. Any thoughts are appreciated.

Thanks in advance,
juxt

My first veg unit and cloner had leaks from the beggining...I tried everything but couldnt stop it. Then i found out why...i had the rubbermaid containers, but i had the wrong style. I then found the right style rubbermaid at wallmart and also used some weather seal and havent had a problem since. Look at the first couple pages of the stinkbud thread. Stink has some pictures of the cloner and veg units...those are the ones you want. good luck.

hey Dirt, i always stop by your thread but never post, i always felt if a guy does a great job no need to comment, we have similar units and your shit is on point, my i make a comment about that discoloration? ok i know i cant help it, but to me that looks like a touch of nute burn with some PH flux, i know your on top of the PH and ppm reads, when i see those symptoms it usually is salt build up, you can check this by running plain water thru your system and catching some runoff from the tube, check the ppm of that. by 5 weeks into a grow you should have lots of salts on the insides of the grow channels and attatcthed to the roots, this can easily make us go nuts, if you ran water at say 0 ppm and runoff comes in at over 250ppm then you should flush, just imagine the 250ppm worth of salts ontop of your nutrient regiment, just my 2 cents but when i see issues like this its usually an issue involving the root zone, btw great grows bro

Subscribed... Great job Dirt.

Well i went with the first draft above witha 430cfm fan, pushing ...so far its been perfect,,,although the weather outdoors seems to dictate the temps...last week my room was a constant 88..this week its colder and its about77....a speed controller might be my next purchase. AS for clones i am at 100% so far..

stinks system is the shit.

reconfiguring my fans for the lights.. any chance u can put up a pic how u got em hooked up? is the fan inside or outside the room??

Chef

Yea my fan is mounted on the outside wall of the flower room. It pushes through all 4 lights in a horseshoe pattern then up into the ceiling. This time of year my ac unit is pretty much on constsntly. I cant wait till summers over, im gonna enlarge the room add 2 more flower units that will use only one res, all one strain, run 8 per rack and add a 1000metal halide on a light mover straight down the center. That way there wont be a shadow anywhere in the room. Only running 8 will still keep me within my plant limits and i will still be harvesting close to a lb per res.

so my res ran dry and i didn't catch it till the tenth hour all my plants were droopy. and the water they received that day before it ran dry was concentrated so i got burned as well. i filled up the res with five gal of r/o ph'd water then mixed ten gallons nuted and all came back in a few hours except one. during the night i thought it would rest and cool of as the fans were out for a coincidence during the time and it reached a hundred deg. this morn the one plant is still droopy three hours lights on. will it survive should i flush and change res can it take a whole day or more to bounce back? and for another question my clones havent poped yet and there 7 days old

anyone? the one plant also smells distinctively different maybe rot somehow before the issue it was so strong ten colas evenly growing should i just junk it or is there a way to pull it and put it in care alone are the roots strangled by the neighbor maybe?

I had a similar situtation once. I had a power out for 10 hours. Once the power was back on the plants all perked up within 24 hours. They still turned out great.
I would just refill the res, bring your ppm up to what you had it at, ph it and sit back and see what happends. more then likely things will turn out fine...maybe you might lose a plant or two..no big deal. I have some clones that take 3-5 weeks to root so patience is a virtue.

only one didn't bounce back i want to save it i lost a lot of under foliage due to this which is ok i needed the hair cut but i want to try to get this one back. have you tried anti wilt. and my roots are brown is this an issue

If the one plant doesnt make it there is not much you can do, beacuse the rest seem fine. By the way your grow looks great! The roots turn brown from the liquid karma,, thats normal.
