answered grow question 6y ago
If they came off towards the bottom of the plant, it is a nitrogen deficiency. If not, since the yellowing and necrosis begins on the outward edges, I would say it looks like a Magnesium deficiency.

I started to worry a bit. My gorgeous plant starts to yellow from the bottom. I don't know if that's normal. I expect another 4 weeks of flowering actually. I hope it won't rot on me :( Any help or tips are welcome ...

Yellowing leaves
Leaves seem kinda yellow on one hand. The bottom right hand corner one looks like she needs CalMag but I'm not sure. All the photos have been taken under the same light. Used to over dose the nutrients to prevent burn but continually gave them 1mL/L calmag each.

Do I have an Iron Deficiency, if so How do I increase Iron levels (Already using Calmag)
I think I have an iron deficiency. New Growth is appearing yellow. HYDRO Rain water - (20ppm) PPM 750-900 (just upped) Canna Aqua A+B Calmag (0.35ml/L) PH was 6.2 (as there was a calcium deficiency so I raised it slightly) PH is now 5.8 (I read lower PH is better for Iron Intake

Shock or Genetics?
On day 3 or 4 of this plants grow a small item dropped on her and damaged the stem. Do you think that early shock is the cause of this overall reaction or should I be blaming genetics?

Hello there, Today I saw that some of my plants have some curled and sad looking leaves (see pic). The soil is pre-fertilized and I currently use normal tap water (p.H. adjusted) for watering. My plants get 18hrs of light a day (approx. 300-400PPFD) Thanks for you help guys :)

Leaves down
Hello,fellow growers. My Royal cheese 🧀 seems to be doing not so well in her second week. Leaves are turning yellow and down. Can this be because of overwatering ? I gave her two litters of water two days earlier and now it's all sad. Please help me out.
