Hi @Tictac789! It looks like you applied some spray during the day, and as a result, this droplet left some yellowing mark. I'd recommend not to spray anything while sun is shining. Hope this will help, happy growing! 👊

Temps seem a bit low, or could be burning from water spots/nutrients.
Seems healthy regardless! Good luck on the rest of the grow!

I think I have nut issues?OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?4y ago

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?Week 3

One of my seedlings, seedling A, is twisting a bit as it grows and has some small lighter patches on a few of it's leaves. The other seedling is growing in the same conditions but very normal in it's growth. Any idea if this is a genetic variation, or an environmental issue?Week 2

Hi there.I’m almost sure it’s a female (pic). I got my first bugs. By the look of it I guess it’s spider mites. What I did so far is spray top and bottom leafs with a neen oil solution after lights out and since I saw it on only 2 of the bottom leafs (removed). Any other tip?Week 12

White/Yellow snipes on leaves? (13th day of growth from seed)I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions.
I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yetLeaves. Veins - yellow between

Hi!
I have spots forming between the leaf veins.
Most are a red/rusty color and necrotic but a few are purplish red and still flexible like the healthy part of the leaf.
The only affected leaves are near the top of the plant but not the very top either.
Do anybody have an idea?Week 9

Manchas en hojaHola!
Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa.
No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos.
Un saludo!Leaves. Color - Yellow
