Notacrimeyostarted grow question 4y ago
Hello,
my plants been manifesting these symptoms all over the leafs (last 2 days). While flushing the 30L coco pots, ph runoff was 6.10, ppm 350-400. Veg day 42. Analyzing my behavior I wasn't watering with 20% runoff, for technical reasons.
Now I will. What deficiency is this?

Most deficiencies are a result of overwatering. When you overwater the fragile roothairs start to rot resulting in them not being able to take up nutrients anymore. Even when you dump in kilograms of Potassium, the plant will still show signs of Potassium deficiency.
This is very tricky as you can imagine. Preventing is the way to succes.
Not sure if this is also the case with coco, i only on grew soil sofar.
GL anyways!

It looks like Potassium deficiency.
Some growers like to flush their grow medium to ensure they are not dealing with other issues, such as overfeeding which can interfere with Potassium uptake. Chicken manure as a top dressing to your grow medium can help, as can a Potassium rich nutrient feed or foliar feed. Organic seaweed is particularly useful as a foliar feed.

Why leaves brown? (urgent)Some leaves turn brown as in the photo. Leaves in the middle turn brown first, then bottom leaves. Now I try making larger lamp-to-plant distance and feeding less nutrients, but no good sign appears. Other conditions are stated in my diary. Why do you think it is?

Brown spots on tips of some leaves4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

Continuing calmag deficiencyWhat I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Emerging Issues - Week 9At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown.
This starts at the tips of the large lower leaves and spreads quickly to the whole leaf.
Also modest edge curl.
What am I doing wrong here, folks?

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda.
Je vous remercie 🙏🌱
