Iron deficiency in container pepperocini
I'm new to trying to grow things and not kill them (aka gardening). We have a pepperoncini plant that had it's first bud appear over the weekend however it also has some serious signs of iron deficiency. Tested the soil's pH and combined with the yellowing of the leaves and a scorched appearance I'm hoping I can help this little guy out. I've read a lot about chelated iron being added to correct the problem but am wondering if anyone has tips or suggestions to help with this.
What we're using:
Three gallon smart pot
Aurora organics potting soil
Once a week feed with BioThrive 4-3-3 formula (It's high in nitrogen and now that I found a few buds I plan on changing the feed to something high in phosphate to get the fruit going unless there's other suggestions)
Watering when the top few inches of soil feel dry
He lives in a west facing window where he can get sun and warmth.
