Have a question and need some opinions

So I'm probably going to transplant my seedlings into their permanent pots sometime within the next week and was curious about something. I'm using FFOF and by the time it's transplanted it will have been about 3 weeks which is right about the time a lot of ppl recommend the start of feeding. But, if i'm going to be transplanting them into larger containers with fresh FFOF should I give it another couple weeks since the nutrients will be fresh?

Yes, the nutrients avalable will support them for another round. Wait a few weeks before adding additional nutrients

Thank you. That's kind of what I was thinking but it seems like a lot of info i've read kind of leaves that part out. One more, what do you think is worst? Not feeding your plants until you see a nute deficiency, or feeding them to early and burning them? I'm crossing my fingers that I start feeding them appropriately but was just curious.

Over feeding can cause damage to the plant that is difficult to remedy. Under feeding will reduce the vigor and thus the yield. I would suggest that finding a comfortable middle ground, based on the instruction on the package, and work with that until you feel comfortable. Then move on to experimenting.
