Are you giving any nutrients yet? Coco coir doesn't contain nutrients so you need to start sooner than if you were growing in soil.

Jaunissement ou brûlure ?Yellowing or burns on 2 leaves on a plant! Could this be due to the lamp being too close? 40 cm
With SpectraPanelX160 X 4 lamps and 2 SpectraBulbX60 with the same 60-watt COBs. The manufacturer Floraled advises me to keep it at 40 cm with the 120° lenses. What do you think? Thanks a lot!

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy diskSudden 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.

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
