Wth is this? It's driving me nuts (4 months now)

[Pheno555]

I have been battling with this problem on some of my nugs for three runs now, I run a perpetual in 7 gal 707 soil.

First I thought it was because I had stopped using enzymes and was getting salt build up.

So I flushed for a few days and started using zym again.
It stopped. (week 5 flower)

Next run with lower ppms and zym, I get it again, I thought it was because I was spraying with the lights on, so I started spraying lights off.
It stopped. (week 5 of flower)

Next run spraying with lights off, I get it AGAIN, and even on the trays that I intentionally didn't really spray. It stopped now, at about week 5 of flower.

So the only constant that I have is that it starts in about week 2-3 of flower and goes on into the beginning of week 5 and stops, most buds recuperate, some stay ugly.

It only happens to like 10% of the canopy.

Now I am down to it being the BLACK LABEL ROOT ENHANCE (which I use from veg to week 2 of flower, at 200% strength) or the new soil I am using: 707 from roots organic.

Does anyone recognize this?

 

[Pheno555]

and no, those are not seeds.

 

[ChasingGreen]

What exactly is the complaint? Is it just the color, or does it look like the buds kind of died for a minute then they recover?

 

[bigblue72]

looks like theres not much frost what are your temps like

 

[KapnobataiZ]

To me it looks like youre plant is tryng to reveg ,litle leafs coming out from the buds,ofcourse it wil not reveg but you will get fluffy buds..to much Nitrogen ,u can reduce the light cycle to 11:30/12:30 or lower. LE : Dont spray youre plants in the flower stage man, u want youre flowers to taste good.

 

[Pheno555]

You are all correct

no frost compared to their counterparts

looks like they died and came back to life

too much green growth instead of flower.

one of the things I am going to eliminate (good guess), is spraying kelp so far into flower, I usually spray up to day 12 in flower and then stop, I think spraying kelp after day 7 of flower can be one of the causes... could it?

Also, it's kinda hot, about 85 degrees, sometimes 87, with good air circulation, 65% humidity (at the bottom of the canopy, not the room, the room is like 50%) and with CO2 at 1800ppm

I have had runs do well with these factors, but I think the kelp is the difference... or the rooter at 200%?

I am eliminating both... I just wanted to see if people could identify exactly what it was.

Thanks so far btw

 

[Pheno555]

here is a pic of the "normal" part of the plants.

 

[Pheno555]

they are in week 6

 

[TheEagerBeaver]

It's almost certainly your rooter at 200%. Eliminate that additive completely. Why do you think you need it?

 

[Granger2]

Cut CO2 back to 1000 ppm. Good luck. -granger

 

[KONY]

Cut CO2 back to 1000 ppm. Good luck. -granger

And get temps under control.

 

[OG Tree Grower]

Nothing wrong with 85f or 1800ppm. I prefer 86 and 1200ppm but those numbers arnt causing those problems.

I agree with to much nitrogen. And or kelp spray
Not sure how rooter could cause this in flower but maybe.
Def looks like buds died off and tried to regrow and that makes me think kelp spray

 

[PoweredByLove]

looks like it's either mag def, or too hot at the tops...i'm leaning towards the heat myself. got any pics of a single plant by itself? or the lower part of the plant?

 

[Granger2]

Are you saying that it's 85* at the canopy or bottom of plant? People are suggesting you try changes to try to determine cause. Kelp shouldn't be the cause, but eliminate it as a cause by removing it for awhile. Your root product at 200% would be the first thing I would suspect, then 1800 ppm, then temps. Your plants are so green well into bloom that I think your soil is really high in N. Are you running CO2 at night? You should turn it off early enough that it goes down close to ambient at lights out. Good luck. -granger

OG Tree Grower,
You say you prefer 1200 ppm CO2. He's using 50% more than what you like. I can't see how you can say it's not a problem. Something is causing him problems, unless it's the wrath of God. Using that much CO2 and 200% root stimulator tells me that our pal has a "more is more" tendency. I wouldn't be surprised if his soil mix is hot, too.

 

[OG Tree Grower]

While I do agree it is to much co2 it will not cause that. I know guys that run 2000 ppm and have been doing so since they taught me how to grow. Wasteful but not a problem.

Remember he said he sprayed kelp with lights on. Directly onto buds.

Yes for sure it sounds like he may go hard on things so there could be a couple little problems here that were not picking up on

 

[PoweredByLove]

people spray kelp on their plants all the way up to flushing, spraying kelp doesn't cause what he's showing in his pics. i've seen it a lot, if you like i can post pics. it's from either not enough magnesium, or too much heat at the tops. based on the crinkle in the leaves that's from too much heat.

 

[OG Tree Grower]

Doesn't matter what you spray, if you do it with the lights on your asking for trouble.

If it was heat it would be more uniformed. That's concentrated in places like water hotspots. Just my thoughts

It only happens to like 10% of the canopy.

this one actually touched the bulb and got dried out.

the rest were just really close.

 

[OG Tree Grower]

I see what your saying. Maybe a combo of things as stuff like this usually is.

 

[Pheno555]

Thanks for the replies everyone.

It might be a combo of factors, because I DO have a mag deficiency on leaves in some leaves/strains, I did not know that was a symptom.

The room is sealed, so even though CO2 turns off at night, it stays over 1000.

Already stopped the kelp, I know some people say they know people who use it, I have used it a lot too, but not all strains were showing the problem, some are thriving with it, so it could be strain dependent.

The soil might be hot in the opinion of some, I top at like 2.5 EC at week 4.5-6, but I have had many good runs and I feed feed flush with tea all the way, also enzymes all the way.

That's why I have been looking in my log for changes, I found: Sprayed Kelp, and 200% rooter. As well as my change to botanicare pure blend pro (already changed back to previous brand) I heard one-parts like pure blend pro tend to be lacking micro nutrients.

These are some pics of them, the good and bad, they are a week from being done.


As you can see the most affected are those further from the light, the popcorns basically, so it's not thee light... maybe the temp.

Trying to get a new AC in this week, the heat started and I can't get it under 87... which still should be good, strain dependent.
