Looks like it's on the new growth. My guess it would be Zinc deficiency.

This looks like a classic case of light burn the top part of the plant seems damaged which is close to the light source.

Yellowing Sugar Leaves
Noticed the sugar leaves on bud leaves are also yellow. My understanding is this can have a big effect on final yield?? Flushed the gal but as no amber trichomes yet and want 20%, should keep flushing now on or resume feeding till some amber??? Cheers

I'm already seeing yellowing and on the largest plant, #3. Is that due to growth or am I over watering? Approximately 2 gallons in the wick bucket every few days when it starts to feel dry, but I generally spray the top with water on a daily basis, not more than a 1/4 - 1/2 cup.

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

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.

Yellow tips near bud sites
Yellow tips are developing on some of the leaves near bud sites. Is this a cause for concern or a sign of a deficiency? The light is as high up as i can get it and it is on max currently. Also the only nutrients I have added the whole cycle has been small amounts of a compost tea

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.
Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?
