Looking like they're stretching well mate , never grown that strain bit as <span class="link_user">@zannabis7</span> pointed out , could maybe do with more light , I don't mean time in light , I mean intensity , I'd move my light closer to the plant as it seem to be using its energy stretching towards the light rather than fill out ... don't panic tho , looks healthy ! .. I noticed your using a 600w is it dimmable ? If so , I'd dim to 250 or 400 and move light closer to plants .. I'm no expert tho mate , that's just tips I've brought from photos

Thanks for the comment! It's 600W HID light. I just watered them last night, and they are looking better now. And I won't be able to find the items you said soon enough so I'll have to skip the transplanting then. But I'll definitely do the 3 gallon fabric pot with perlite thing with my next grow!
