Yea, it was about 15 bucks for the 5 pound bag (at my nursery). After reading back into my grow notes (finally found my notebook), I completely agree with you about the bloom foods. For example, the last Skunk I ran was fed with only the 5-5-5, probably could have used more but the majority of green leaves stuck around, this time, bulb food was used and my leaves are still yellowing (almost all larger fan leaves are gone). So, guess you could say I did an experiment without knowing it.
Do you think I could stall the yellowing if I added some blood meal to the mix? I'm worried she's gonna be butt-naked before harvest (roughly 4-5 weeks to go).
