First year hops- leaves look burnt

[thomascbucher]

looking for some help. First year cascades I started off in a 24" pot. Some of the bottom leaves had some burning early on which I figured was due to overwatering. The plant overall is doing well, but some of the burning appearance is carrying up the plant. Any ideas?

It's in miracle grow potting soil, has 25 3/8" holes for drainage, is reading as moist/wet on my moisture meter And has 2 primary vines climbing.

I have been using plantone organic 3-4-4. I have put about 3 applications on top of the mulched soil in about 4oz amounts.

Go easy on chemical fertilizers. They can leave slats in the soil that'll harm the plants if too much is used too often. Also, in warm weather months, when you water them can burn them too. Water in the early morning or late afternoon/evening to help prevent this.
