It's probably just from a water droplet or the soil splashing up on it. I've seen it on my first set of lower leaves where they get splashed from watering. Just keep a eye on it.

Raise Calcium up to 150ppm (2ml/l calmag), try not to point the fan directly to the plants. Peace

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

Am I taking the correct steps?
I think this is due to a combination of overwatering (1l per 24 h in 60% Light-Mix, 30% coco, 10% perlite) and possibly overfeeding (used close to recommended dosage). I have let her dry out for almost 2 days and today watered 0.5 l plain water ph-ed to 6.5. What do you think?

Yellowing Leaves? Nutrient deficiency? Fixable?
Is this a nutrient deficiency? I'm 3 weeks into flowering. 2 or 3 weeks away from harvest. I'm using Biobizz Grow, Bloom and Top Max. Is it an issue that can be fixed? Or do I just need to get it right next time?

Rapid yellowing of some leaves
I've noticed strong yellowing of some leaves overnight. It usually happens to the lower leaves, but in my case the whole plant is pretty flat, so there's no real distinction between lower and upper leaves. Is that just flowers taking up nutes from lower leaves or some deficiency?

Is this a CalMag deficiency?
It started with White Widow a few days ago, showing signs of yellow leaf tips. I'm quite sure I'm not overwatering. Are they overfed (nutrient burn)? I use plain water and applied Zamnesia Monster Bud Mix (Pellets) to the soil before the grow. Scared for my first harvest.

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :D
I read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?
