Growing Rocket, also Arugula/Rucola

Hi, I planted rocket seeds in a large pot with organic soil about 3 months ago. They sprouted very quickly then when they were about 1 centimetre they went purplish colour. Now 3 months later they are only about 2 cms high!!! (In another pot (about 3 months ago) using the same soil I planted seeds from same pack - these grew to about 2 inches and didn't go purple. BUT they haven't grow anymore!!) I tried everything, not watering, watering, adding fertiliser, leaving them in constant hot sun, not so hot sun...but the purply ones have not budged!! I took one out and the roots are about 4 inches long though... I am wondering if I should just start again?? Thanks anyone who can help!!

Same thing happened to me they grew to a small size and stopped growing, my issue was over watering. Now I use a moisture meter about $10-$20 from large hardware shops . And they do very well. Also Liquid feed fish/seaweed every 2 weeks. Try digging out a bit of soil down to the bottom of your container and see if it is water logged?
