My sister doesn't compute, and I don't raise AVs. Here I am trying to help her out. She's having a problem with thick leaves coming out in the center of her plants. We're both [almost] sure it has to be the fertilizer, but she is using both soil and fertilizer she purchased from an AV farm. She is using the latter in the recommended amount.
She has already tossed 22 plants after cutting leaves and is now ready to toss out the entire collection. I suggested she cut the amount of fertilizer by half in the water. I'm sure others here have addressed this before, and I promise I tried to do a search, but it didn't go anywhere.
Can someone please help. Thanks so much.
