Yellowing from edges of leaves to base of leaf

Eagersstarted grow question 4 years ago

Having trouble diagnosing this deficiency, EC in is 1.5 and PH is 5.8. Growth of buds has completely slowed. a week ago looked like I locked out potassium using 1.75ml/l calmag in feed so flushed now using normal calmag. Runoff ph has suddenly changed from 5.7 to 5.1 and EC 0.5

Also should add its mainly just this leaf (others have all sorts of issues left over from lockout) but this is curling down and yellowing from the tip back toward the base. I read that too high ec can cause ph to drop really big but Is 1.5 ec too much mid flower?

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color

Leaves turning light green -- yellow (after 12h day/night rhythm)Since I started with 12h daylight/dark rhythm a lot of leaves started to turn yellow (older and lower ones first, some branches turned red). What I did: PH value=6.5. I added CalMag--no effect. I flushed the soil --no effect. Do you have any ideas? Thx green thumb-friends 👏

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On 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?

Leaves are turning into dark green with a plastic-like texture I have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩

First timer seedling worries.First time grower, is this normal for a seedling? I'm currently on day 3 and noticed these guys have some dark curling leaves. Is this caused by over/underwatering? A light issue? Or am I just over worried? Soils feels moist. They are in Tupur, lightly buffered, in 1gal growbags.
