Your plant leaves appear healthy. If just the stems are turning purple, most likely cause is from intense light. Nothing to worry about.

Is this a magnesium deficiency? The stems seem red. If so, does Calmag do the trick here?

Deficiencies? Brown spots, yellowing and purple stems
What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Purple stems on some seedlings?
Why would the plants on that edge of the tray have purple stems? Nutrient deficiency? I noticed the one I checked with a purple stem had more roots showing from the rockwool cube than any others... think they're trying harder to get to the juice cause they got shorted?

Deficiency or toxicity
Stems are really purple, leaf stalks and veins also purple. Something is up. Some leaves starting to show burn spots but not many. She's a bit down because she needs a feeding. Is this magnesium deficiency? Should I be upping my nutes at this point this late in veg end of W9?

Autoflower week 9, not flowering
So what should I do, there's no signs of switching in week 9! I've tried changing to 18/6 lighting, but have only been running it for a couple of days. Besides that she is really droopy and the soil feels really hard (maybe lots of roots). Any advice is appreciated :)

Is it nutrients? Light?
What can this be? The stem is red, and I thought it could be over lighting (I had 2 LEDs of 200 W each), so I removed one of it. But now I am also wondering that it can be nutrients, no? If so, how can I solve it? Let me know what you think. It's an autoflower - 7 weeek.

Help needed - harvest time?
Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.
