SaintSativaanswered grow question 6y ago
What I would try first is to bring the ph down to 5.5 - 5.8. The 6.7 its at is out of range for dwc and proper uptake. Good luck

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 🙏🌱

Was haben meine Pflanzen?Dear community,
Newbie here :)
I have two Critical Kush Autos in their 7th week that have had slight necrosis/discolored leaves since flowering.
Unfortunately, I only fertilized for the first time with Hesi Bloom 5ml/L three days ago, not at all before that.
More nutrients? Less light?

Is this a deficiency or light burnHi all my other plants are perfectly fine except for this one it has brown edges on the leaves and has been growing the slowest out of all my plants and I was just wondering how I could fix this? I checked the run off PPM yesterday and it was 1100 so I flushed it and now its 700

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.

K deficiency? Or something else?Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

Too much light or other deficiencyToo much light or some other deficiency?
I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.
