Sounds like a nutrient lock-out, or possibly toxicity, likely due to a pH imbalance. How are you measuring the pH of your soil and water? The pictures above, that is very likely what is going on, a pH nutrient lock-out. Check that runoff ph. 🤘😤

Also looks like a phosphorus deficiency, but like the other guys said, if you aren’t watering with runoff or enough of it or you aren’t checking your runoff ppm and pH a flush is probably best

Rust inside the main fan leafs like that is exactly that ph soil and water. I would do a sledge flush and evaluate.

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 others Im 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

Identify Issue: Brown Spots, Lower leaves first, from outer-tips Showing up on 2 out of the 5 in my soil bed. Front 2. Transplanted 10 days ago, went well enough.

Spotted Leaves My 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?

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?
