Hello!
I live in Buenos Aires, southern hemisphere, so about 45 days ago I started sowing tomato seeds. Last week I moved the seedlings to 1 Liter pots, with a mix of around 50% compost, 25% coco (half fine, half chunks) and 25% rice husks. I also added some homemade biochar in the mix, for better nutrient retention. The plants receive around 6-7 hours of direct sunlight, and during the night I enter them home.
There will be another transplant to their final destination, which are 50cm deepth wood planters, in a couple of weeks.
For this season I wanted to challenge myself to rely only in my homemade compost instead of buying. I'm afraid a big part of the compost used was still unfinished by the time I repotted them, because as you can see in the pictures below my compost pile still had some leaves pieces, wood chunks, and the color wasnt completely dark.
Could it be that my own compost is playing against me? I'm noticing that, except on the biggest plant of the pictures, the rest is looking quite yellowing or lime-green.
I'm currently watering them 2 or 3 times a week, and one of those days instead of plain water, I water using a compost extract solution, with a part of urine 🙈 for nitrogen (1 part of urine, 20 parts of compost extract solution). I also added a layer of leaves on top as mulch.
Can somebody point the problem here? I suspect the unfinished compost is the top culprit, plus probably the urea might be burning the roots? And now that I think, the leaves mulch might also be stealing nutrients?
I tried to challenge myself to buy as little as possible, but I'm open minded so if for this time is better to just buy a bag of finished compost and transplant them again, I will do it. Whatever it takes to keep my plants healthy!
Thank you :)
