New growth yellowing? Or am I paranoid
I'm really unsure if she's getting what she needs, New growth kind of shows a deficiency maybe? Using 4-4-4 and 2-8-4 Organic mix in the soil. I'm about to buy stuff to make a compost tea for them. She was healthy up to week 3, now showing this yellowing 🤷♂️ Thanks for help

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!

Hi all! I was checking on my plants and noticed one of them is showing yellow/brown spots in some the top leaves, only showing on 1 plant but I’m nervous it’s leaf septoria?? The plant is in week 10 and is my last pic on week 10 diary. Does anyone know what this could be? :)

Wilting and yellowing leaves after vinegar water solution
I sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳
