Bugs or Calcium deficiency?
MamaSheastarted grow question 4 years ago
Bugs, Calcium deficiency, or something else? A few brown spots on one fan leaf (3 of the 5 leaf affected). Nothing i can see on magnifier. No webs. Nothing noticeable on any other leaves; either plant.

Looks like calcium defiency, some sort of cal-mag should do the trick.
I use general hydroponics, cali-magic, 1-0-0 for autos as it is not as high in nitrogen as some other brands.
Hope this helps👊

I'm by no means an expert, the opposite in fact but I have noticed similar spots on mine and every single time it was "water lensing" focusing the sun (i'm growing outdoors) and burning them. Nutrients will always burn the leaves if you are not careful while watering. In my case the yellowing never progressed beyond where it originally manifested and and I haven't had any new yellowing since I started paying the necessary attention to watering.
Are you sure it is not something leaf specific? If it's insects try looking underneath the leaf, this is where most insects leave their eggs not atop. Let us know how it progresses. Cheers!!! 😀

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

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.

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.

White spots on a few leavesAny idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

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.

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?
