Advice requested concerning pine seedlings

[Bowhuntmuledeer]

I have a handful of seedlings I started late winter and moved outdoors a few weeks ago. It’s hard to capture in a picture, but they don’t look very healthy. I’ve lost some for various reasons, but these all seem to be hanging on despite looking questionable. The cotyledons are normal I understand, and the newest needles seem to be a healthy shade of green, but some in between look off colored. I have been fertilizing with a pretty dilute dyna grow bonsai pro liquid plant food 7-9-5 Would greatly appreciate your feedback.

What is home climate zone please? Add to profile along with home town. Is soil too wet or dry? Are trees in Sun or shade?

Mine look like this when it's super cold and when they're over watered (or lacking oxygen in the soil).

Update on these guys! Not sure how big they’re supposed to be, but one really took off in the summer! Here’s a pic of the biggest and the smallest. I think I was over watering. The sand/floor dry/pearlite mix would be dry on top mid afternoon after a morning water, so I would hit em again. I cut back to one watering a day and I think that helped. Even if stunted this year, I think they’re getting setup for a successful growing season next year!

How many hours of sun do these get?

How many hours of sun do these get?

Probably 8-10 hours. It’s probably been a little less later in the summer, as some peppers and tomatoes shade em out a little earlier in the afternoon. The spot where I initially had em would have gotten all day except early morning, but a rabbit chewed on em and I moved em into the garden until I get the little tree area fenced out; which isn’t as high on the list of things my wife wants done around here

Hard to really tell how bug they are with nothing for scale but the larger one looks good for 1 summer.
Huge growth is not always desirable for bonsai anyway. The low branching on the bugger one is a better start than many straight stems with no low branches. The small one should produce a number of shoots from the tip in spring which will also give you future options.
Slow and steady is often better, even if unintentional.

Thanks! There are inches marked on the right side of the paper, but they’re not overly useful because of the camera angle oops
