Cant Figure this out!

[bigweedo]

So, half of my plants keep showing these signs of yellowing, spots, def. and nute burn! One plant's fan leaves are pretty much all gone, and the rest have some medium yellowing. Here are the pics, help is needed!

P.S. The ph is 6.5 and the last time i watered was 4 days ago with half a teaspoon of 0-13-14 and half a teaspoon of 3-0-3. start of 3rd week of flowering.
Thanks,
BW

IMO that may need to be a bigger N boost if shes vegging id go with a 10-3-3 or the like something that has more N in it and then when you flower you still need the N but higher P-K something like a 5-10-10 this way shes still getting her N and some P-K for vegging and then more P-K during flower

Thanks for the reply. Just gave them a nice little drink with 3-0-3. Ill include 2ml per liter of water for the next feedings and see how things go. Any other opinions/suggestions?

DabbaMan pretty much summed it up... you need to be giving vegging nutes during flowering as well.
