If that’s just the bottoms, I wouldn’t worry—- looks like there might be soil on the underside of the leaves? Flip them and make sure you don’t have spider mites.

Veg Nute Issues
Has anyone seen any diaries that catalog a successful sick veg -> healthy flower recovery? I'm curious to see how sick growth transitions to healthy growth over several weeks. Current issue: a) LED intensity, b), N excess, c) PK def, or d) cal/mag def(rust on leaves top and btm)?

Blätter gelb und fallen ab Blütewoche 9
I'm really worried about my plants right now, a lot of leaves are turning yellow really quickly and falling off on their own even though I'm fertilizing with every watering. Should I fertilize even more and water more often? The buds look good so far, but there are still more white hairs than flowers.

What do you do if your run off ph is hi6.9? I've started using bloom nutes so it's going in at 6.0-6.2. Will that be ok or do I need to flush with ph water down?

Fellow growers, after a few weeks of beautifull growth, I now start to get yellowing leaves which dry up and starve. I am. I am doubting between a lack of nutrification or over nutrification. I suspect the latter (biocanna nutrients and soil). Any ideas? Thanks!!

Yellowish color at the tips and wrinkles
My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

Yellowing leaves help please (newbie)
Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?
