Hi folks,
The lowest leaves have been yellow for a while, possibly due to a combination of inadequate nutrition and high pH (tapwater about 6.5-7), which I've been treating with fertilizer every week or two. Over the past few days, even the upper leaves (of all four of my plants) have begun browning and yellowing along the leaf margins (irregularly), and curling up a bit. It has been very hot (30s Celsius) and humid the past few days, and there was a thunderstorm last night. I fertilized last night also, and for the first time added 10mL of vinegar to my 10L watering can, but the final pH was only 5.5 so I doubt that caused this. Of note, a disease is rapidly killing my tomatoes, planted nearby, with similar features, and a similar time course, so I'm concerned this is an infection.
1) Pics (of several plants):
(whole plant)
(one leaf, top)
(one leaf, bottom)
2) Growing indoor or outdoors
Outdoors, on a windy balcony.
3) Watering schedule
Depends on conditions, but generally when the top of the soil is dry, though not for the past few days due to concerns about encouraging fungi.
4) Growing Medium
Standard potting soil.
5) What stage of growth
Vegetative, roughly 8 weeks.
Your advice is much appreciated.
