Starting Fox Farm Nutrients

My clones are a little over 5 weeks old. I purchased them and have had them vegging for about a week and a half. I was planning on starting to feed them with the FF nutes today. I have the feeding schedule printed out from the FF website. I am not sure which week I should start on. I plan on vegging for 1 more week or so and then start flowering. Is it ok to start on the 4th week of the schedule, which is 1 week before flowering? Or should I start on week 1 of the schedule and then skip weeks 2-4 and go straight to flowering schedule next week?

if you are already 1 week into flower would you not want to start flower nutes?

My bad. I meant Vegging.

I have 2 vegging now at 36 days from seed. I've been using the full line of FoxFarm products in soil.
I gave them the first 1400 ppm feed 2 days ago. gave them 2 feeds of 1/2 strength before getting to full power.

No ill effects to report at this time

happy growing
