Q.What’s Wrong With My Raspberry Plants?
I live in zone 7 and have some berries planted in 20gal containers. The varieties include red, gold, and purple raspberries 1 blackberry and 2 tayberries. Currently my blackberry and tayberry have developed an issue that I can’t figure out. I have these planted in a mixture of peat moss with compost and pune needles as mulch. I pre fertilized the soil prior to planting.

There is, definitely, a pH or nutrient imbalance. Unfortunately, you won't be able to tell by looks, alone. Testing your soil will reveal what it wrong.
