issue with leaves, should be easy to solve w/ my info?

Thanks for your help in advance. My bottom leaves or yellowing and slightly curling but the rest of my plant is looking great. I'm worried it'll be the beginning of something.

Pics, I've been using 60-30-10 Potting to verm to top soil. Nutes are pure blend pro 3-2-4 for veg. A month or so old about to start flowering.

What strength are you running. Looks like the beginning of N deficiency. Boost some N, should go away in a week.

boost some n way early for bloom nutes ..looks healthy nothin to sweat
