Gritty Mix Tree Leaf Size Question
About 13 moths ago, I barerooted several citrus, cherimoya and other sub tropical fruit trees and planted them in the gritty mix. I've since fed them with foliage pro 9-3-6 and Pro Tek 0-0-3 pretty much every watering in the dosage of 1 tbs every gallon of water. However, I've noticed that most of these plants in gritty mix grow new leaves that are much smaller than same trees grown in regular peat based potting soils. I feed them pretty much once a week. Are they under- fed?
Anybody has an explanation or solution? Any insights from Talpa?
