Moisture/Humidity/water Stress? Or Something else...

[Maggs707]

Hey guys, this is my first indoor grow and my first time growing Key Lime Pie. The girls seem to be bouncing in and out of some type of stress induced state. It seems that when the soil is completely saturated after feedings/ waterings the girls show symptoms that at first glance would seem to be an overwatering issue. However, I have been growing for going on 10 years, and have a pretty solid grasp on when and how to water. These girls definitely get their dry cycles. My solutions are always pH'd at 6.5.

Symptoms include curled down leaves that "taco" at the same time. Growth seems to slow down and the girls just look limp, pale and tired. Some leaf stems are a dark red (might be strain, not sure). The older growth doesn't seem to be affected nearly as much as the newer leaves.

After watering, the humidity levels in the tents seem to be varying between 75% to 85%. I know that this is generally high, but I'm not sure if that is what's causing the symptoms that I'm seeing here. Any help or insight would be super appreciated!

Strain: Key Lime Pie
Lights: Spider Farmer SF4000 LED's
Medium: Happy Frog
Pots: 7 gal smart pots
Nutrients: Full strength SeaBlast Transition, CalMag, Sea Green, MicroBlast.
Stage: Week 8 of Vegetative growth, soon to be flipping to flower.

Over watering would be my first thought after seeing the pics. Humidity is a bit high but manageable with the right amount of air flow. Didn’t see anything mentioned about temps. And happy frog is good soil all on its own. Additional feeding really isn’t necessary. But after 10 yrs of growing, I’m sure I’m not telling you anything you don’t already know.

I appreciate the reply bro. Temps are low 80's in the day, and low 70's at night. Happy Frog is great! I would be curious to see how a full run would turn out in HF with no additional nutrients. Have you done this?

Too hot, too much N, too much water/moisture?

I tested the soil and the NPK levels are in range. I would think that it was a heat/lumen shock issue but it happens after I water/feed and then slowly gets better as the pots dry out. I've grown dozens of different strains and had all kinds of issues, but never a girl that "pouted" after being watered. It's messing with my soul bro.

It looks like too much heat/moisture. The plants don't want water because they are getting too much of it through the air. Getting an a/c and dehumidifier to keep your temps and humidity at a constant and where they are suppose to be will stop almost every issue. An uncontrolled environment will always have issues. I would still back off from your nutrients, at least nitrogen.

I opened the tents up and got some really good airflow between them and they're looking much better. I think you hit it right on the head man. With the humidity that high, they're not craving the water. Makes sense! I'm not sure if that's the only issue I'm having, but it's for sure part of it. Is there any specific reason that you think I should cut back the N?

I like my plants with the dark green leaves and nuclear green tops, its way better than being lacking, but its riding borderline overdose. Having heavy nitrogen is dangerous in high humidity and heat it causes burning and tacoing of the leaves.

Another thing I see happen after flipping is feeding a different type of nutrient, the bud base, and the plant can't handle being stacked up with so many different nutrients and chokes out the first couple weeks. If you use the same veg food for the extra stretching during the flip I think it is less risk. I think what I am trying to say is give it some room for the new food and a reason to uptake it.

I have my theories on that change in nutes when entering flower... I think this may be why the feeding scheduled say to flush in between cycles... to push the veg nutes out. I could be wrong.. I smoke and think way too much! *Lights a doobie*

You're giving me some gems here I appreciate it. I'm using SeaBlast Transition, and nothing additional for N. It's more of a high P blend. I do have those nuclear green tops though, I'll keep an eye on it. Totally different topic, but have you ever had bud sites pop up in early bloom that look brown? Figured I'd ask you while I have ya on the line! Thanks again

Hey bro, gotta follow your gut and do what feels right for your girls! I can see the methodology behind the pre-flip flush.

Depends on the brown, like dead brown? Are the leaves effected by it or are they just carrying it? It could be a spore/mold of some kind from high humidity. Or just like woody stems. Can't be for sure.

I personally don’t think a pre flip flush is necessary. Then again I grow in Coco where the goal is to get runoff with each feed which essentially acts as a flush. If there is still too much residual nutes then you are either not getting enough run off with each feed and/or running too hot.

Most bloom nutrients also lack N, which is still very important during bloom and why many growers plants start fading way too soon in flower. I supplement veg nutrients during bloom and taper off halfway through flower.

It's like the same brown that an apple gets when you bite it and leave it out.

Sounds like the bud sites could have molded from too high of humidity. Mites have been known to eat the chlorophyll from buds also, resulting in the death brown, but there is other signs of their presence that would show first.

 

[The Gram Reaper]

Definately not mites, I can't really tell from the picture and I have to leave for the day. Could be a result of humidity or PK lock out, but its hard to tell. Very sorry, I will check back later.

I was having humidity issues. The girls are only in day 5 of flower, so I guess I'll just snip off the brown pre-buds and hope the new growth doesn't do the same thing.

 

[The Gram Reaper]

They might just need a chance to dry out it could be over saturation. If you are only 5 days in the plants most likely have a lot of growth/stretching you should be good.

It was Russets. Figured it out a little too late.
