could very well be magnesium in an early stage.. if you know you have soft water, then i'd definitely recommend adding calmag..
i have very hard water, so i use an RO filter to remove all the impurities, and then have to manually add calmag to each watering as well

Hey gardener! From what I've seen online, you have a magnesium problem; you should add more. When the leaves turn light between the veins like that, it means you're lacking magnesium and need to add some. If your branches ever turn purple, it's definitely that. Good luck to you, bella ciao!

Buds zu klein nehmen nicht an größe zuI've been having problems with bud formation for quite some time; they are too small compared to the other plants. The leaves have a yellow discoloration that goes from the outside in and shows unevenly on the new leaves. Auto Duck 4 weeks into flowering.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light SoilOn my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

The most common yellow leave will be found on the terminal stage of flower because plant will power up for flower produce rather leave grown. Leaves are most of the time a reservoir of H2O nutrients and minerals.

Calcium deficiency or overfed?Hi.
This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress.
Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain.
Thanks!

Upward curling of leavesOne of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Defoliate yellow leaves?Should we remove these large yellow crusty leaves near the soil? The plants are at about day 38. I've heard people say you shouldn't defoliate this early in flower. Should I be concerned about these leaves dying off or is this normal?
