Cupping leaves
BuddyBudsterstarted grow question 3 years ago
Hi there,
The leaves on the GSC and Monster Zkittlez are cupping a bit. I had the fans blowing on top of them so I already moved the airflow away from the ladies.
Is this that so called "windburn"?
Would like to hear from y'all and thnx in advance

My bet is it's your humidity. I've experienced this as well in low humidity veg.

The heat in the tent is around 25 C° and humidity around the 40%. The lights are on half strength.

Das schaut auf den ersten Blick ein wenig nach Hitzestress aus, finde ich

Mixture of wind burn and on nitrogen toxicity line. The one with shiny leaves is already there. Cupping or tacoing inward is too warm as well. 82F is as warm as you can go without co2

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.

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?

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.

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
