German balcony - Soil vs Hydro - Royal Jack Auto

Starting the 2nd week of vegetation! So far everything is looking very good! The hydro plant is lacking behind a little bit, that's probably because of the low concentration of nutrients. So today I mixed a new batch with 2ml/L TA Organic Grow, which was recommended on the packaging for the growth phase. The roots look healthy, having reached almost the bottom of the jar already. Day 12: The diagonal leaves are starting to come out for the soil plant. Day 17: The hydro plant continues to fall behind. There is also build-up in the jar. I'll be switching to an anorganic fertilizer later today to hopefully stabilize the plant development.
