I just recently decided to jump into growing a few edible plants on the balcony in my apartment. I built two fairly large self watering containers on the balcony, one of which contains mixed varieties of lettuce and the second, a 5 gal bucket, hosts two tomato seedlings and two jalapeno seedlings.
Tomato and Jalapeno container:
I used potting soil in all planters.
All plants have been in this setup for about two month, the lettuce is growing slowly and I'm starting to see a few tomatoes as well one solitary jalapeno appear between the four seedlings that I bought originally.
I'm a little concerned that I'm doing something wrong, however, and was hoping that the community here could help out.
1. Tomato plants
One tomato plant is not producing any fruit and both have a few leaves that are yellowing/drying out towards the edges. From the reading I've done online this could be due to overwatering or a deficiency in magnesium or calcium. Not sure if it's possible to identify the problem through the leaves but there's some images in the link below to help out.
2. Jalapeno plants
There is one jalapeno currently visible but there were far more flowers on the plant than this. A second jalapeno had actually started growing but has now stunted.
Again, overwatering? Under? Not enough food?
The lettuce is coming in fairly well but the leaves are showing areas of white spots that don't look right. The lettuce is in a totally separate container but used essentially the same soil.
I water these containers from the top with a 1/2 gal of water every three to four days and they obviously have the water reservoir at the bottom of the self watering containers also.
I have not put tarpaulin over the top of the self watering containers as the instructions state to do so I water from the top to keep the top of the soil dry. Is this too much? My next step is to put tarp on the tomato/jalapeno container to see if that helps. The lettuce, which I grew from seeds, is still a bit small to do this, however.
I've not put any fertilizer/plant food in either container since I read that it would need to be fairly specialised to work in a self watering container.
Any advice would be greatly appreciated since it's hard to correct whatever it is I'm doing wrong when I don't know what that might be :/
In case you have trouble seeing the images linked above, here's a link to the gallery of all the images:
