Little dark spots - leaf tips curling under?

[Joe Shipman]

The plant in question, Feminized (white castle) from nirvana seed co. she looks like a sativa dominant approx 12-14 weeks old, grown outdoors (container)

Fox Farms Potting soil
Tiger Bloom Nutes
Water consumption (GAL a day more or less) (3tsp nutes per gallon) every third watering

avg daytime temps 88-92
avg nighttime temps 68-72

other than these dots seems pretty healthy

started flowering about a week ago, still growing pretty strong just these damn dots and curled under leaves.

Im thinking if I get my PH checked and balanced might solve it but I dont know much so seeking help here thanks, btw dots are not typical of the whole plant probably only 5 or 6 leaves showing symptoms

Looks like a slight (since you say only a couple of leaves are affeceted) calcium deficiency to me. And your daytime temps are bloody hot, if I may say so, which might account for the curl.

You might want to add which exact nute formula you are supplying.

Apart from that, she looks nice and healthy. Maybe someone else has more input?

Thanks LEDMAN yeah it is pretty warm here, not alot I can do about that. I may move her to a spot with a little less sun see if that helps. I checked the PH today and it is around 6.5

(NUTES) FOX FARMS TIGER BLOOM 2-8-4

only thing perplexing me is that the little AF sitting right beside her is doing fine (no curls no purple spots) same treatments same nutes (pics)

thanks again for the input will keep an eye on her

Hmm... if conditions do not worsen, I'd count it off as some temporary imbalance and nothing to worry about.

Cheers!

Something that I tend to notice is that those black plastic pots get hot like hells bells in the sun... I'M TALKIN HOT YO!
You may consider painting them or transplanting them babies into smart pots or?

The roots are baking, this will cause your leaf curl... she is trying to keep moisture.

That's my 2... peace out!

 

[Joe Shipman]

Yeah thought about that, what do you think about putting a damp towel or burlap around the pot? Eveaporation from damp cloth should cool it down

 

[Captain Kronic]

You could also put ice on top of the soil on those hot days and just let it melt into the roots... I know that would feel good to me!

Maybe a piece of of mylar or somthing, even cardboard would deflect quite a bit of that nasty heat... cheers!

 

[Joe Shipman]

here ya go LEDman and Captain Kronic, my 7$ solution white towels soaked in water will use those during the day to shield pots.

Bugs? Seeing any shininess on leaves.?

 

[Joe Shipman]

lots of leaf miners here but other than that no other bug problems I see

think I burned her pretty good hopefully she will recover seems to be only on the leaf fans not on the other stems and nodes
