Stains on leaves. Due to pH? Roots look fine I guess
DeadwebsiteBoringcommunityanswered grow question 4 years ago
It's your tap water.. Read your local water report.. Find out how much Calcium you have in your water.. If your at 150 ppm from the tap... It's probably got a lot of Calcium in it to begin with.. This is caused by calcium excess and can slow down your growth.. Ph problems display up top. Fluctuations aren't bad anything too low or too high will cause visible damage.. But if your checking daily...

Hi,
this is a tricky question. Your problem can be cause by a lot of things, try trouble shooting your plant.
Check Water ph, humidity, heat, bugs. If non of this is the cause then you jump into nutrient deficiencies.
Check out the link below and it might help you on how to identify your problem.

Gorilla Cookies Auto - But Purple?About 2-3 days ago my Fast Buds Gorilla Cookies Plant developed some purple pistol hairs (photo). However Gorilla Cookies shouldn't be a purple plant, except for the leaves? Is this normal, a rare genetic mutation or did I get a wrong seed?

Is this a Male?Hey growers out there,
all my plants already have white hairs, the TP1 doesn't have any yet. It also looks a little strange and I'm a little worried that it could be a male. What do you think? 😰
Its Tropicanna Poison XL Auto. Never had a male before, only banana herm stuff.

New growth looking strange and growth slowed down (wilting?)The new growth of my plants are looking a bit strange, and growth seems to be slowed down.
Could this be that the light is too strong? Or can this happen if the humidity is too low?
I already installed an humidifier but looks like its not helping.
Whats going on?

Will this tape repair a broken stem?Should I re-wrap this broken stem? Bent with too much pressure and there was a snap, though not completely severed. I applied two or three layers of duct tape, not sure if the constant pull of ties will allow it to heal and repair. When should I take the tape off?

Plant Topped Itself at 3rd node? Stress or mutation/morphology?This plant split into two shoot apical meristems at 3rd node, I think? Is this due to stress, or a plant morphology/mutation? Pic 1 = weeks before pic 2. Pic 2 = 3rd node & 2 stems. Pic 3 = strain name.

How tall will they grow to be?How tall will these outdoor untrained, soil based photoperiod plants grow to be (best rough guess)?
I believe they're a sativa-dominant Sour strain (either Ultra Sour or S.A.G.E and Sour bag-seed).
Currently over 1 meter tall from soil at 60 days old in 7 Gallon pot.

Fall RecoveryHow is the seedling looking? She took a fall yesterday afternoon and I immediately rescued her as I could and repotted into final 3 gallon fabric pot (actually 5 gallon but only had enough Coco Loco for 3 gallons). Thank you for the read, happy growing and learning. :)

Is this a sign of a hermaphrodite?I'm afraid one of my plants might be hermaphrodite.
Today i spotted something that looks like male pistils.
I removed them carefully and found something similar at the plant and removed it aswell.
Should i remove the plant from my tent (3 other plants are inside) or keep it?

18 weeks, but I'm not sure she's ready.The plant is 18wks old. Leaves are getting yellow, some buds are so fat the branches bend under the weight.
I'm worried some pistons are still white and I can still see some clear trichoms, but she's 3 weeks after the recommended date of harvesting.
Do you think she's ready?
