im pretty confident in your plants. both of my plants have stretched to a point where i thought they couldnt be saved... and i saved em... they got to a point where the stems were so weak that they couldnt stand at all. an idea, use bendy straws to hold them up as long as the stems still thin enough. it workd wonders for me! also tying them helps. and they will always lean toward the sun. thats the light source, and the leaves absorb the light, so its a given itll lean toward them. mine do the same with the grow lights im using because its not right over them
