Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
oppilFstarted grow question 4 years ago
So, I have 3 plants:
- 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light.
?? The left plant is showing a few defects. Anyone?

Seems like a light Potassium (K) and Phosphorous (P) deficiencies - yellowing from bottom to the top, chlorosis, and blotching on a flowering plant.
Try increasing your "TerraBloom" to about 3.5-4.5ml/l (start with 3.5 and slowly increase to 4.5 if gets better).
The PK consumption of the plant increases immensely during flowering!!
Hope this helps! Good luck and happy growing :)

She telling me a calcium deficiency. Calcium is best absorb when ph is 6.2 to 6.5 hydro soil 6.2 to 7. If you suspect your growing cannabis plant has a calcium deficiency, flush your system with clean, pH’d water that contains a regular dose of cannabis-friendly nutrients that includes calcium. This will remove any nutrient salts that may be affected the uptake of calcium and help restore pH to the proper levels.

Edit: 90pct of the leaves are looking swell, but just 3 leaves you see appear to be having these issues... they get the same nutrition as my other 2 plants who are doing fine..

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?

Sligthtly Yellow LeavesI'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Is this Stating something or is it paranoyaI had a few leaves that were turning yellow, but they are lower leaves that are slightly yellowish on the outside, generally the plant has become a little lighter since it started flowering.
Am I worrying too much?
