Been vegging 2 weeks in FFOF in 6" pots and watering with RO water only and some calmag, no nutes. Very healthy and crazy growth so far. Just transplanted to 10" pots using FFOF soil again. About to start LST now and start flowering in 2 wks or so. Are there enough nutrients with the new/additional FFOF soil from the transplant, or do I need to start using nutes soon? If so when should I start to follow the FF feeding regimen (I know I need to start with a 1/4 of the recommended amount)? Will be using the FF nutrients. Thanks.
I would wait a week and a half to two weeks to start feeding. The soil has enough nutrients to feed them that long.
