I’d highly recommend not using much extra nutes with FFOF early on through veg. Oppot before flip and you’ll be good, may need some help in later flowering. I def wouldn’t use liquid nutes with FFOF unless the plant isbig. I fried , and I mean fried, 2 plants that way.
If you do decide to start using liquid nutes, start small.
Also my current grow the plants are also very stout. Check my journal:
Goodluck
