MistaOCanswered grow question 1y ago Hey! It's always a bit tricky to make an accurate diagnosis without knowing some important details (e.g., pH of the watering, EC value, temperature, etc.). But I'll give it a shot based on what I see:
1. pH: It looks like the pH might not be quite right. If it's too high or too low, important nutrients can get blocked – that's called "nutrient lockout." I would recommend checking your watering and adjusting it to a pH of about 6.2. Especially with LightMix, that's a good value for the plant to absorb everything it needs.
2. CalMag deficiency: If the pH isn't right, it can also cause CalMag issues – and these often show up as spotted or yellowing leaves. If you're watering with very soft water or reverse osmosis water, a little CalMag supplement would definitely be a good idea.
3. Fertilization: You mentioned that you just put the plants in LightMix a week ago. While it's pre-fertilized, it doesn't last very long – after about a week, you should definitely start lightly fertilizing. The girls might simply be hungry.
4. Watering: The plants also look a bit overwatered. Make sure the soil dries out well between watering. Heavy, constantly wet substrate can lead to root problems and slow growth. Sometimes less is really more.
5. Pot size: The proportions look like the pots might be a bit too small for the plants. If the roots don't have enough space, it can restrict growth and cause other problems. You might want to transplant into slightly larger pots soon. Are the roots already coming out of the bottom of the pot?
In summary: Check the pH, start with light fertilization, pay attention to the watering amount and frequency, and consider larger pots. They should recover quickly!
If you want to go into more detail, feel free to message me. However, I'll need all the data from you to make a detailed diagnosis.
