Well, your diary doesn't give us any information, does it... are you growing in soil? Coco? Hydroponic? It's probably a magnesium deficiency - check your PH... if you're growing in soil, it should be between 6.2 and 6.5 ... preferrably 6.2. And add a dose of calmag to your nutes but only once a week... Good luck.
