It looks like a zinc or mag def. Not totally sure. I had a problem that looked similar to yours that was caused by the ph being to high and it locked out some nutes.

I would give them a good flush and some fresh water and nutes in your res. Don't go too strong with the nutes till you figure out your problem.

I've use this thread as a guide, but hands on exp. is the best teacher.
 
pH has been steady now for a couple weeks I have been though the link you included and it looks like a couple different issues...
 
? TDS how many ppm are you running RO water city water???????????????
Looks burnt to me flush and start with new batch of nutrient maybe a little lower than what you are running.
 
thanks its just on the older leaves new growth looks good...I will change rez tonight just plain pH'd water and maybe some rhizotonic...would you use 1/4 nutes or plain water for a few days?

Flush and add 1/4 nutes, maybe a lil stronger considering the size of your plants, just keep it on the weak side till you get a handle on things. I've grown years without a tds meter, but they r recomended. I grow a strain i am familiar with so I know what she likes. May consider lowering ph down too 5.2-5.5
