Newbie looking for Kratky advice : hydro

Hi! I’m a first time hydroponic grower just a few weeks into the process. I’m following a Kratky method that I found online, but have made a few minor adjustments because of limited availability of supplies.

The setup:

I’m growing a romaine lettuce blend in a dark 10 gallon plastic container, eight total 2” net pots filled with clay pebbles. PH is 6 and I’m using Fox Farm ‘big bloom’ and ‘grow big’ nutrients.

The article said I should trim all but the strongest plants once they sprout but that seems to make the remaining plant kind of lie down and sometimes wither. I tried not doing that on my youngest plant and it seems to be doing great. Any thoughts?
