I’m not a big fan of foliar feeding period… it’s use as needed … if I want to cut the stretch down I’ll foliar spray bk in the 2 weeks of transition… or if the plant was over watered why add more water then I’ll do a foliar feed till the soil dry up some ….. the only time I would use yuca is if the soil dried out and I don’t want dry pockets in soil Or if I’m gonna be out of town and it will miss a watering ….. but this is me… what others do is on them …. Another fun way way to learn tho….. ohh I will foliar trigger to help with bud sites , week before 12/12 and 2 weeks in transition…and remember only foliar when lights off .. hour after lights off or 1 hour before lights on .
