Please don't take offense to this, it is not meant that way. What you really need to do is to read and study about growing. Your plants are certainly not the first to have this issue. There is literally thousands of posts with the same issue. Read the stickies, tons of great info there. Once you have spent some time doing this I am reasonably sure you will have your answer. Posting a pic and just saying "HELP" is likely not gonna get you much more than more questions like what soil, nutes, lights, temps etc etc and even some rude comments. Good Luck with the grow and +rep for taking the leap into farming!
