What are these big white blotches on my leaves?
ShiftyGaijinstarted grow question 4 years ago
First soil grow. Haven’t been keeping track of time or writing down notes on this one. Just getting a feel for how the plants grow in soil. Some of the fan leaves on one plant have pretty big white blotches on them. Curious what anyone else thinks.

hice mate, look like a fungus or a mineral deficiency. I suggest you cut the affected leaf and apply some foliar nutrient formula

That looks like rust, a fungus.
Organic fixes:
baking soda, 1 tea spoon/ quart of water. spray on.
copper sulphate, read lables.
fungacidal soap sprays;
garlic sprays, 1/2 cup minced garlic, 1 quart of water. let sit 24hrs, strain, spray.
sulphur, one of the best natural sprays. it is low in toxicity.
micro kill, a citric based killer. great success
Remove affected leaves if possible.

Normal trichomes or something bad?Dumb question, I started noticing this on my leaves. I recently battled with insane humidity which I was just recently able to fix, and was wondering if this is normal/my usual over worrying or if it's some sort of mold/mildew/fungus or something I should actually worry about.

1 out of 3 doesnt do as well as the othersIm just wondering why one out of 3 plants, does not perfectly well while the others seem doing awesome. Can it really differ from a strain that it shows signs of light stress or nutrient burn while other plants seem to do well with it?
I added 3 pics, 1st one showing the meh one

What is this Jawn on my Leaf Device?What is this on the leaves? Brand new clone 1 hour in my ownership. I sprayed her with Bonide Captain Jacks Copper Fungicide in case it is PM. Doesn't look like PM though. Looks almost like hard water deposits. What do you guys think?

Identify Issue: Brown Spots, Lower leaves first, from outer-tipsShowing up on 2 out of the 5 in my soil bed. Front 2. Transplanted 10 days ago, went well enough.
Watering with tap water, never tested but didn't have an issue last run. Same soil, but I did add 8 cu ft of new soil to the top. Gently amended with b6, Kashiblend, coconut powder.

Brown/white spotHi everyone. The plant is a photo on her 7th week of veg. I give solid ferti and diluted compost tea water then appeared white spot on old leaves and the new leaves have tips burnt.
Is it PH problem or PH mix with overfed?

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?
Info in week 10.

Spotted LeavesMy ladies looked good until recently, it has been very warm the last few days. Then they began to let their leaves hang down (didn't get enough water) and gradually turned yellow, now they are getting spots. This is my first grow and I am not sure what it could be.

Tiny holes!?This morning while looking I noticed tiny little holes on some of the leaves on one of my plants. I didn't see any pests with my eye, and I tried to use my phone the best I could but couldn't see any. I've also heard this could be environmental/viral. Any thoughts or ideas?

Leaves pointing upHello,
One plant has most of its leaves pointing up. Plant look healthy otherwise. PPFD is around 650/700 and light pattern is 20/4
What could be the root cause? I read mixed answers. Some say healthy plants and or strain specific other that light stress.
