you need to get a small fan blowing on them to strengthen them. But first provide some support to get them standing up straight. Also how far is your light from the plants?
well if i were you since there tilting try doing a lst grow, and if i were you just make sure everything is spot on, like your waters ph, temperature should be like 70-80 degrees, get a fan, and make sure your light is about 6 inches from the plant
exactly. Ive found it works best for me to wait till like node 4-6. your results may vary depending on your setup and that though. maybe try 1 early and try 1 later and see which one does better for you.
