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

Maggs707 said:

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.

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

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 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 thing 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

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.

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


Kind of like when you bite an apple and leave it out type brown.

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.

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.
