Dark Green, Dry Leaves.....

[SunnyD]

I got this plant here, forgot how old. She was always dark green, but recently the leaves have gotten dry and feels papery. few yellow spots popped up to. also she is curling.... Just transplanted last night into 2.5 gal containers...Thought she was root bound and that was cause the curl...temps are 85-89f around high 60's at night.

Mine have the exact same yellow spots like that, just random...I'll bump!

I want to know what I'm doing wrong also

 

[DOVESPRINGSGROWER]

thier flowering to me it seems normal as its useing all its energy to produce bud other then that i would say PH Problem

 

[closetexplosion]

thanks dove, that has run through my mind a couple times, but still the ph tester is still being shipped...(don't know when it's going to get here, still early so maybe today!) Add Vinegar for pH up, and Baking soda for down right?

Ok I hope your strain is suppose to have evergreen leaves. Because evergreen leaves especially in the flowering stage is a sign of final phase of nitrogen toxicity. The most common culprit is people using incorrect doses of time released fertilizer. Another common flaw is that they are still feeding the plant too much nitrogen when in actuality the plants needs have changed where it requires phosphorus and potassium levels significantly higher in comparison to the plant's needs in its vegetative state. I would flush immediately with 2-3 times the volume of your container with water or water mixed with a flushing agent like clearex. Also introduce an extremely mild form of nutrient cocktail since after the flushing you have removed the toxicities and also nutirents your plant desires to utilize.

Flushing time-released soil is a disaster...why I haven't done that yet...going to transplant to FFOF in a day or 2 and try to gently shake the soil from the roots and hope that rids my problem of the time released nutes...will never use MG again...

i've been feeding once a week using 1/2 strength Maxibloom....never fed it in veg.

the seemingly random burn spots on your leaves are due to the MG time release balls in the soil, the roots get burned by it and it shows up as spots on the plant. Since most of the soil is normal potting soil only small parts show burning. MG Nutrients are very hot (Burn) fertilizers to use for MJ plants. its hard for the plant to get used to due to it only fertilizing when it is watered. Transplanting to FFOF soil may well do the trick. be gentle getting the old dirt out of the root ball. You can use a hose to knock some of the dirt off, just don't go full blast. Once you have it transplanted do nothing except straight water for the first week and see how it holds up, then you can start a mild program of bloom nutes for the next week and increase the strength a bit each week until you are at full strength. Looks good so far.

my plant looks the same... https://www.rollitup.org/marijuana-plant-problems/107574-dark-curling-leaves-problem.html

Thats not the reason....I"m using organic soil...what u may be talking about is the balls of perlite...The nutes are General Hydroponic brand maxigro for veg and maxibloom...I do agree it may be some sort of burn...i'm waiting for a few days to flush...I transplanted from a gallon pot to a 2.5 gallon pota few days ago....

The curling at the tips usually means nute burn, do you know if they have been getting any of their micronutrients?

looks to me like heat burns from spraying, They are a little dark which in general is fine imo during flowering. I would say if you mist stop and lower nitro levels so the buds get fatter and theres less juice going to the leaves.

might be from misting. I transplanted a few days ago...lets see how she takes to twice as much dirt....

I think Calicat is dead on. I have had this issue several times and trust me it gets a whole lot worse if not corrected. One plant got it so bad, the buds stopped growing and she died soon after. Mine was a lot worse than your pics but the dark leaves are a very telltale sign. Flush and kill the nitrogen in your feeding.

No its baking soda up vinegar down. I wouldnt recommend using baking soda, My plant was jacked up a few times until I went with a real hydro ph up and down. The vinegar was fine just not the baking soda

it almost done, never got better. havent lost any fan leaves.. it exploded once i adding my 400.....i'll keep u updated, i think this is a strain that doesnt like a steady feeding of nutes....i feel probably 1 out of every 5 watering would have been good enough.
