I agree with akgrown and rd116. I too use FFOF mixed 2:1 with additional perlite. After 1 month I mix veg nutes per the feeding schedule at 1/4 strength and feed every other watering. After 5 weeks I go to 1/2 strength then go to full strength after week 6. I also use Bonticares Liquid Karma and Cal Mag Plus every other watering, rotating between the 2.
This is how I alternate feedings:
feed with nutes
water with Liquid Karma
feed with nutes
water with Cal Mag Plus
repeat...
My feeding schedule that works for ME:
All tap water PH'd to 6.2 after mixing is complete.
VEG (Grow Big, Big Bloom, Liquid Karma, Cal Mag Plus and Super Thrive @ 1 drop/gallon)
Weeks 1-3 No Nutes
Week 4 1/4 Strength Veg nutes
Week 5 1/2 Strength Veg nutes
Week 6 Full strength Veg nutes, continue until you flip the light
BLOOM (Tiger Bloom, Big Bloom, Open Sesamie, Beastie Bloomz, Cha Ching, Liquid Karma and Cal Mag Plus)
I follow the feeding schedule at full strength, including additives until the flush. (Open Sesamie burned one of my mystery bag seed strains, but all others love it!). I also continue alternating with the Liquid Karma and Cal Mag Plus.
Plain PH'd tap water with dissolved sugar the last 10 days and I end up with clean burning, beautiful plump ladies every time.
