I am a first time hydroponics farmer starting out with romaine lettuce. However, they seemed to have grown tall instead of full.

I used 900ppm of nutrients (water was 300 ppm). 2 parts nitrogen, 1 part calcium, 1 part epsom salt, 1 part 15-15-15 NPK mix at 6.0 ph.

I have not yet connected my water or air pumps so it's now running on the Kratky method. In the pics you will see seedings which were 3 weeks old planted in the hydro setup for 2.5 weeks. The green house is made of shade cloth only, of 50% shade. The plastic isn't installed as yet.

The type is red romaine so you may see some maroon/bronze looking colors on some of the leaves.
