Looks more like pest damage. Maybe thrips. Check bottom side of leaf for small bugs, sometimes you need magnifying glass to see them.

I see signs of thrips and an early calcium deficiency. Have you set some yellow sticky traps to see if you've a pest infection ?

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency. I'm in early flower
Losing a bunch of yellow leaves during early flower. I have WPM but it wouldn't progress like this would it? I think I may have just been underfeeding or my pH is off. What do you guys think?

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

Leaves are turning yellow during flowering - is this an overwaring issue?
About 1,5 week into flowering the leaves have turned yellow, especially on the outside. The leaves in the middle are still oke, lower older leaves are dry. Could this be overwatering or something else? I gave around 1L/day, coming from around 0.5-0.7l/day the week before.

Nutrient burn, magnesium def, light burn? Leaf tip yellowing but not turning brown/curling
4 week since planted autoflower, both started getting this at the same time. First time running autos, grown in FF Happy Frog soil. Soil was used for 3 weeks in a different grow so nutrients may be needed. Light burn, mag deficiency? Have only used ph 6.2-6.5 water, no nutrients.

I’ve got a little greenhouse grow (I think this is a seedsman lemon auto), but haven’t been able to give the plants as much love as I would have liked this year. I’m a bit worried about this one, any advice would be greatly appreciated if anything could be salvaged?! Thanks

Magnesium Deficiency ? How can I fix it ?
got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!
