Twisted Leaves?

Noob here trying to figure out why my plant has a few twisted leaves.
They're green and look healthy, but some of them twist like a corkscrew towards the middle to the tip.
It's to the point where the underside of the leaves are upward.
Take a look at these photos....



Strain: Blueberry
Medium: 1 Gallon Smart Pot with 50% Fox Farms Ocean Forest / 50% Perlite
Lighting: 18/6 with 2 x Area 51 XGS-190 LEDs ~18-20" above canopy
Nutes: GH Flora Series - Have only fed 1/4 (220ppm) strength nutes about a week ago. Plan on giving 3/4 strength nutes soon.
Watering Schedule: Every 3-5 days - I wait until the pot feels lightweight and the soil is pretty much bone dry.
Temps: 72-77 daytime / 64-70 night time
Humidity: 20-40%
Soil PH: 6.3
Tent: 4x4 Tent
Ventilation: 160cfm exhaust and passive intake / two 6" fans in the corner

This plant has been in my care for about 2 1/2 weeks. Since I purchased it from the dispensary, it had slightly twisted leaves at that time. I didn't think much of them, but they haven't changed. I thought they may just get better over time.
Does anyone have any idea what this means? I tried to search but I'm coming up empty. Thanks for your help!!!

When was the last time you hit them with cal-mag? Could also be ph IMO

They've never had it. I though the PH level was fine. In Ed Rosenthal's Growers Handbook it states that an acceptable soil PH range is from 5.5-6.5, ideally between 6.0-6.3. I was going off of that info.
Thanks for your help

could just be hot soil,i have some growing now with few leaf like that,figured my soil was a little hot,from reading here,people siad they will grow into it and not to worry

Yes heat stresss can cause twisting. I doubt you have any micro nutrient deficiencies this early in.

That's what I originally thought it was since I bought it as a clone from the dispensary, but I noticed a new growth that had some of the same twisting going on. The temps have never gotten above 79 degrees.
When I watered the plant without nutrients, I used tap water that has a reading of 37 PPM.

That's super clean tap water.

I dunno about running soil ph with gh flora. I run mine in coco - promix hp and so I am around 5.8 - 5.9 more hydro range.

Best of luck in your endeavor.

I've heard of a lot of people using GH Flora in soil so I thought it'd be fine?

With my tap water only being at 37 PPM, should I be adding CalMag or Dolomite Lime? Could this low of PPM be a
Another plant in the tent (Cheese) has been showing what I think is a CalMag deficiency? It's receiving the same 37ppm tap water between feedings. Is that what this looks like...?




Thanks Snaps!

6.3 seems a little low for soil? My vote is PH



My tap water is right at .14 EC and I need to add in Cal/Mag, I am also in coco which has a higher demand for calmag.

you say you water with 23 ppm tap water. this may be leeching out nutrients really fast and shocking the plant, giving you the twist in growth. try doing 1/8-1/4 dose for "plain" water

I bought a CalMag supplement today at the hydro store and I plan on giving them a foliar spray of it when they wake up in 2 hours.
I will be adding it to the water/nutrient mix also, but I don't want to give them water just yet since the soil is still a bit moist.

I had similar problems. What was the outcome? Did the Cal Mg help? And just JFY, you're going to want to foliar spray a few hours before your light turns on. Also, I'm not sure if you want to use cal mg as a foliar, anybody else doin' that? Thanks for postin'!

My leaves are doing this as well. Just for them as clones from store. Please update about the cal mag as I am on well water so not getting any in there.
