Here is one ischia black i have that i have been experimenting with giving full dose of Miracle Grow fertilizer along with plant in Miracle Grow soil that has a slow release fertilizer in its soil and superthrive supplement liquid mixed in plant is on cement walkway in full sun. Each time the soil dries to where it needs watering i give it full dose of the above. Below are 3 pictures of the small plant that is struggling with FMV and growing very very slow until recently it did start to grow somewhat and thats only somewhat better as i did notice bud open to newer leave and form and do this several times in a shorter time , the other top bud showed a green leave starting to peek out but only to stop and die but the bud itself seems to have another shot at putting out another leaf i have observed. The other picture hard to see has a bud on lower part of plant that just came out and i will watch this one carefully to see the signs it will show. This is something i enjoy to experiment and watch, time will tell if i kill it or it does better as i will keep doing what im doing to find out.
Cmzrdog thanks for your plant, its the one sent out to the lab , Dan thanks for your plant this is the one i have been working with and pictured. Im hopeing the lab one turns out and this one i have time will tell what it does if anything from all the fertilizer its trying to ingest.
