They do look a bit over fed so I would agree, just give them plain pHed water this time, then next time feed at a lower dose.
FDs schedule assumes 8 weeks start to finish which is why he recommends no nutes after week 6. But your plants are going to take longer than 8 weeks, probably 10 or 11. So continue feeding until you see the fan leaves really start to yellow. Then it will be time to flush.
Also, if you have some unsulfured molasses, I would add 1 tablespooon per gallon the next time you feed.
