act now and save the plant . or feed the plant the proper nutrients and have it survive . its as simple as that . what i do suggest is . i posted 2 websites to you . read them and look at the pictures and then try to find your issue and you will understand what is going on instead of posting on here getting GOOD advice then decide to second guess your self and others . you need to be independent on this in the future your expose to have the ability to see what the plant wants and keep it healthy if not then you ask people on here for advice and not follow it letting the plant dye . what ever you decide to do is the correct thing to do no matter the outcome , next time you can do it different and see if you can keep a plant alive for then entire grow .
