one old leaf at the bottom? If isolated, i'd ignore it.. a plant does shed a leaf on occasion.

It looks like one of the older leaves which happens, but also looks like it’s had some liquid spilled on it at some point as well. Not much to worry about at the moment. The others seem fine

Plant seems to be dying, should I flush? And if so, any tips?
Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.

If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?
If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine? Humboldts Secret nutes, Glueberry Og Auto, rh48 temp74-76, advice appreciated.

Light burn
I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

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?

yellowing leaves at the seedling
Dear community, this is my first growth, so I feel a little nervous. On the pic of day 10 you can see the leaves started to turn yellow compared to the previous day. Is it normal?

what is the problem?
The colors of the leaves make me think. I don't give a knock during these weeks of bloom time. Do you think this is a lack of calmag? or this is normal:)?

problems with clones!
Friends, tell me what's wrong with the plant! I don't understand it's under-feeding or over-feeding! At first I thought it was a cal-mag deficiency, then I saw a purple stem and thought it was a phosphorus deficiency! Now I don't know what it is anymore! at the very beginning it

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?
