Other Comments:
Id just like advice on lettuce, as there isn’t many NSW based growing tips, and general tips for cos lettuce :/

Answer:
Hi Jacob, I am struggling with your problem since there isn’t much information in your email for me go on. The soapy water would make lettuce wilt and turn brown. If you failed to fertilise the plants for 2 months as you claim, that would produce very poor growth. By 2 months, the lettuce should have been full grown and harvested. I hope that this helps, Don
