Cause of skinny new leaf fingers? Started a week ago or so but all the new leaves coming in have been had very slender/skinny fingers.. PH IS GOOD
elevensixty6started grow question 2 years ago
Was doing research and what I found was either P excess, low humidity levels, light stress.. or just the Savita genetics? The plants are all in good health, growing fast and do not show any signs of deficiency aside from the skinny leaves forming. PH is fine, its living soil..

This is completely normal for some strains and quite common when flowering.
It is thought that growing narrow leaves in flowering makes it easier for pollen to "find" the femalw flower pistils and aid in fertilization.
It is not a nutrient, pH, temperature, humigity or lighting issue, just a normal occurence and nothing to worry about.
I have grown dozens and dozens of plants that have done this exact thing when flowering and have come to expect it.
Your plant is fine, there are no issues to be concerned over regarding the narrow leaves in flowering, it is a genetic function.
Hope this helps, Organoman.

Mmmm... you say the pH is fine - do you actually measure it? If you use a pH pen, have you calibrated it recently? Have you measured the pH of your runoff to see what is actually going on with the pH in the soil?
Really skinny leaves are a sign of zinc deficiency and while sativas have much skinnier leaves than indica, these really are pushing it... Skinny leaves, yellow tips, beginning to twist ... these are all signs of zinc deficiency and this is caused by pH issues... specifically a pH that is much too high. If you haven't been measuring it and just assuming stuff here, water until you get runoff and then test that run off... if it's over 7.0, you'll need to do a flush to get her back down to the 6.4 you say the pH is and then keep carefully monitoring it the rest of the way.
Good luck!

I think this is the fault of relatively excessive light

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?

One odd seed - super slow and tiny plantI'm curious if one of you know why only one of my seeds CC Girl Scout Cookie from the same set barely grows.
pics for comparing: both are in the 5th week of veg, both germinated at the same time received the same soil mix and sitting in the same growbox. Any clue what happened?

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.

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.

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?

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?

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.
