Dying quickly! 5th week flower Sour Diesel.

[Esther]

Ok well I definitely screwed this up somewhere. Being a n00b sucks but I'll get it someday.

I "flushed" my 9 Sour D's over the last 4-5 days. I put flush in quotes because I only had about 5 gallons of RO per 7 gallon plant I had. And I didn't even ph the water because I figured it was just a flush, and that the ph'd nutes I watered with right afterward would correct the ph. Probably stupid, I don't know, and maybe that's not even my problem.

Anyway, after "flushing" (and I had watered with only cal-mag+RO for 2 waterings previous) I gave them a big helping of everything: PBPB Soil (just 10ml/gallon), LK, Calmag, Hygrozyme, Sweet, and two new things - a half dose of Roots HPK and a normal dose of Canna Boost.

In addition to what you can see in the pictures, they also have softened up consideralbly and stopped smelling as much over the last few days. The pics are of the worst, most progressed plant.

What'd I do wrong?

And one in the early stages...

The whole garden...

I know about the PM...I'm working on it. And actually, the burnt pistils you see I THINK are from the sulfur that I just vaporized a week ago for the first time, but they COULD be from food, I'm not sure. I just picked up a PPM meter from a buddy so I'm gonna test my run-off.

THANKS FOR READING THIS FAR!

I'm new to the scene, but could that be nute burn? It looks like you're growing soilless.. If you didn't do a full flush, and then added a full dose of nutes, wouldn't there be buildup of the nutes that didn't get completely flushed? Just a thought..

Have you tried a full flush since the symptoms started showing?

What is the lowest night temperature you are seeing recently?

Are they on a basement/concrete floor?

Low temps will cause lockout and look like cal def...also plants will fade to light green/yellow...

You mention the PM which is caused by low temps and high humidity....

Your plants would greatly benefit from you raising the pots off the cold ground and putting down styrofoam or packing skids for the plants to sit on.

no airflow at night in a tightly packed enclosure during flowering can cause a lot of def/tox nightmares too, from the transpiration back feeding interfering with nute uptake, not to mention the onset of pm.

Are your exhaust fans running full time overnight ?

ps...that's quite a mixed cocktail you're feeding.

btw...off topic, we'd all be better off if you didnt use outside photo hosting services like photobucket.
For one thing, it's a security risk for you. You'd be way better off uploading pictures here instead.
Secondly, the members who view your thread wouldn't get hit with such a sluggishly large load to see the pics.
I'm on broadband and viewing this thread just about choked me out.

Well your going to have to find out what the PH is of your soil. Its not a good idea to flush the soil and then start adding supplements back into the mix. If your PH is in lockout territory then it doesn't matter how much supplements you add your just going to be making the soil more toxic. Usually those red dots on leaves are signs of calcium deficiency but that doesn't mean you need to add more calcium its mostly signs of PH lockout. Figure out what your PH/PPM your working with before messing with adding stuff back in.

The ph of the runoff is 6.00. What's the way to fix that? Feed with above-7.0 water or flush or just keep feeding with 6.5-6.8 and have it slowly correct itself.

Also, the ppm of the runoff was 850, so my nutes aren't very high.

 

[Esther]

Bump! It's getting worse!

 

[TurboBob]

shit, I'm gonna say just from the basic information that you provided it's a deficiency of sorts. You state that plants were fine, then you flushed and then this showed up. You still haveb't fed them nutes and you say it's getting worse. Maybe that one flush had bad ph so they are experiencing lockout with the remain nutes in the soil. I would reccommend doing what you were doing before this problem showed up

Could be LSF, I have a few plants at the moment covered in it.

y0 my pal stAx knows this styrain well, will direct him over this way after we smoke l8r.

betting the horse on MAG deficiency.

why did it lock out? i dunno...

flushing and not using primary nutes can lead to lockouts, but also a high PH will make mag less avail.


One thing i stick by since i heard it way back yrs ago and i still do it today, is when using R/o or anytype of filtered water is that CAL/MAG must or should be mixed into the batch of water 1st thing. them stirred/swashed, whatever u do.

This will ensure a proper buffer already present before mixing the nutes in and checking the PH.

If i were to mix the nutes first into my pure water, especially when dealing with organics, that would toss my PH for a freekin loop....meaning not really ever stay stable and bounce up and down a few tenths. adding cal mag last might help the ph be more stable, and work for some, but is in my assumption that the latter is the more correct way to do things.

dont know if this has any relevence to your situation but figured the info seemed worthy and i like to pass little reminders all the time =) g/L

Your runoff is 850ppm.....The RUNOFF! Yes your nutes are high. To have that high of a runoff is not good at all. 850ppm = 1.8ec. I feed my plants with those type of nute levels. My runoff is NEVER that high. You need to do a FULL flush! Then leave them alone for awhile. You should flush with a mild nutrient solution. Something like "final phase" that helps clear the root area of all toxin`s. Then test your runoff and see what the ppm/ec is and go from there.
