always difficult to tell for certain in pics.. grow lights impact colors we see etc..
veins are fine. they shouldn't be dark. ratio of nutes probably off a bit as you never really progressed beyond 5-fingered leaves.
this is more complicated in soil to diagnose. in soilless you more precisely know what is given to the plant and therefore easier to observe and adjust. pros and cons to each method, this is simply a pro of soilless and not meant to warp your preferences.
both have to give roughly the same mass of n/p/k/ca/mg/s + trace elements per week or per month etc... law of conservation of mass. different growth rates would require differing total amounts needed for that growth to occur. so, this is a simplified concept that is nonetheless true but more complicated in action with more moving parts.
but, you fertilize diffeerntly with soil and soil has its own nutes baked in. so it's supplementing the soil's contents over time.
anyway, i am more familiar with soilles. you fertilize every irrigation with 10% runoff to maintain a 1.3-1.5 EC concentration of well-balance diet in soil to match growth on demand.
check out a leaf symptom chart and mulder's chart -- you can see how complicated finding the right ratio can be. some products start you closer to optimal than others. it has nothing to do with brand name nor ingredients.. simply ratio of ingredients. fertilizer components are ubiquitous commodities. there is not "top-shelf" ammonium nitrate.. it is simply molecule-for-molecule ammonium nitrate no matter what brand slaps their name on it.. same for MKP or cal-nitrate, or ... fill in the blank.. . soil nutes can have varying quality, though.. those products that vary a lot will not come with a guaranteed analysis label.
