That's almost definitely the effect of excess heat and/or humidity. It also looks like there could be the beginnings of a Cal-Mag deficiency, as well, but this may just be remedied by adjusting pH to 6.4 or so. Good luck!

Cupping
On the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?

Leaf Curling and yellowing on three week old plant, how to stop this gettign worse?
I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

I'm having some sort of mold issue I think. I cant figure it out I havent seen anything that looked like this. I've Googled leaf symptoms and molds but nothing looks similar enough for me to say that's it for sure. Any help will be greatly appreciated!

Leaves curling into bud
As sugar leaves send their nutes to the buds and start to curl/die, do I need to trim them off before the curled part reaches the buds? The fan leaves were an easy choice to trim...sugar leaves I’d have to trim the leaf rather than stem. Is that ok or necessary?

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Nute Burn? Or something else?
I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

This is a 27-day auto plant. The problem is that the leaves are crunchy and curled upwards. Soil pH measurement 6.5. There was a fan right in front of it, I changed its direction 1 week ago. Do you think this is a disease?

Tips curling up
I noticed the tips beginning to curl up. I did gave her bio grow in the last two weeks 0.5ml/lt ph 6.5 almost every watering i used bio grow. I have another 8 plants of different breeds and none of them showing anything wrong. I wander if its the nutrients or perhaps the light?
