Hello fellow gardeners,
my White Widows are sick and I fear they won't make it. They seem to have a severe infection from bacteria, but I also cannot exclude a fungus infection. I may have overwatered them, especially when I thought I had given them too much fertilizer, so I rinsed the soil.
It all started with brown stains like shown above. Then the leaves got burned from the sides (see next picture). Also, the plants started smelling less than before and they grew very slowly.
It got worse before I decided to cut off all affected leaves. However, the disease came back quickly.
To the day, I find stained leaves every day. The upper leaves also started loosing their healthy green color again, turning yellowish. The tips of the leaves are reddish-brown. There also are holes.
The only good news is: the red leav-veins turned green again after the last watering with fertilizer. However, the plants seem to have almost ceased drinking water by now.
Is there anything I can do to save my ladies, or do I have hold a funeral and start all over again?
I think you may have overcorrected with the flush after trying to balance the excess nutrients. Broadly, it almost looks like it's a sulfur deficiency? Difficult to be sure through photos, and honestly it matches a few possibilities so I don't really know for sure.
The drooping really feels like a watering issue. How damp is the soil if you go down a few inches?
I don't give up on plants very often, preferring to run them into the ground in the hopes of learning something, but I'm not positive this one can be saved.
The first inch is bonedry, but it's damp below that. Soil moisture is about 40-50%.
Apparently, my plants have all kinds of deviciencies. I should have used more fertilizer and better soil. This is almost pure coconut.
How's the drainage?
I guess I watered too little. I did it in 3 steps:
That way, there was almost no run-off.
I use BioBizz BioGrow (an organic fertilizer, but also feasible for hydros), but it turned out: in too little quantities, too.
