@guywithtrees I do but am having issues uploading for some reason. I think maybe it's getting a little too much sun combined with a drop in humidity given it is our winter here and the cooler temps could be part of the problem. This is it's first winter outside even though it's still in a pot. Will be putting it in the ground come summer. I have another already in the ground and it's going very well.
I measured the PH seemed to be fine. Although my meter is a super cheap one from Amazon. I have been watering everyday cause of the black grow bags. Fish emulsion and Epson salt weekly maybe twice. They are coming back. I did move the smallest yesterday it wasn't happy not being in the sun. These plants seem to LOVE the sun. I still have patches of green yellowish leaves. When I water they only get rain water. I have a homemade water collector from an old water softener. Here are some new pics. You will understand the smallest plant was definitely in the wrong spot.
I've had this problem a number of times over the years. I usually just make sure my Soil is acidic then I give it a dose of iron and nitrogen. Problem is you have to wait a couple weeks to see if what you're doing is correct. Fish emulsion is great for that or you can go straight to ammonium sulfate, Which is what I use because I have so many. But you do have to be careful with it I have burnt a plant or 2 in my day.
@roadkill I tried to add new pics but there is an error. I wanted to stay away from Miracle Grow but gave it a try. In a week they bushed up and are coming back beautifully! I am going to use it 2 times a week for a few weeks. I also tried coffee grounds for about a month with not much result.
@guywithtrees yes. Actually I only use rain water. I have a home made catchment system. I use fish emulsion. I have tried Miracle Grow and they are coming back. I have a bunch of pearlite in the soil so it will not dry out, I did not use a ton of grounds.
