Nutrient Burn?

My plants just entered flowering stage earlier this week, so I switched my ferts. I fertilize once every 7-14 days depending on how much rain we've gotten, so this was the first fert since beginning flowering. The plants are well over 6 feet and I only used half the recommended dosage, which is the same I was doing for veg. They've been incredibly fast growing and healthy since being planted. But this evening I noticed some yellow spots developing on the new growth. Doesn't look like nutrient burn from what the Googler showed. I also was reading about leaf septoria (fungus) but it seems that should start from the lower leaves and go upward, this is just on new growth. Both plants. Pics attached. Thanks for any input

Doesn't look like nute burn to me either. Not sure if it's septoria, usually it's more advanced when I see the pics on here and your spots are relatively small. How much rain you been getting?

Cheers for the replies. Just wanted to add some better pics here. When I took the first ones there was terrible glare from the sun on my screen and I couldn't tell how clear the pics were while taking them. I don't think it's a pest because some of the blades are growing this yellow color as well, right from the plant. The reason I thought maybe nutrient burn was because that's the only thing I've changed in the last 24 hours. Gave them ferts yesterday, today these yellow marks show up, and not really local, they're all over the plant. We've been getting some more rain than usual, but where they are they also see a decent breeze more often than not, so I don't think it's a moisture issue. Anyway, rambling, clearer pictures. Thanks again
