answered grow question 6y ago
How old is she? First things I'd check are the soil and then the nutrients. The soil looks like it could do with better aeration but to me she looks hungry.

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy disk
Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Nutrient lockout?
Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?

Little seedling having a hard timr
So guys; I'm worried about this seedling. She's having trouble on keeping up with her sisters. I noticed a yelow color on their tinny tips 🤔 Cotiledons got brown pretty quickly too. She took longer to "open" the cotiledons after popping from the soil. Should I do something?? 🙏

Warum werden die Blätter auf einmal so schnell gelb und welk?
Hey, meine Hawaiian Runtz ist Ende 4. blütewoche. Gießen tue ich alle 4-5 Tage mit 2-2,5 Liter Wasser und 6,5 ph Wert, immer ziemlich identisch mit Terra aquatics ph Tropfen, also sollten ph Fehler ausgeschlossen sein. Temps am Tag ~28 und nachts 26 grad Celsius. What’s wrong?

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.
