How much do you think we pay for things we really don't need to grow a weed? It's a weed, you know, those things we are always trying to kill on our lawns but never succeed. We seem to constantly be searching for the magic bullet that will give us results we only dream about.
Light is the plant's food...everything else are supplements.
Of course you need water to go with the light, but with that in mind, how big is your collection of nutrients, supplements, voodoo juices, snake oils and bloom boosters? I have some stuff that's been sitting around unopened for over a year. As for soil, I use scott's premium for container plants. It's cheap, readily available and works great in my opinion. I'll never buy another bag of foxfarm or any other pro sort of mix. I am trying to let my experience replace the mystery and voodoo that surrounds growing. That's why I started giving my girls advanced nutrients big bud tonight...I'm still looking for that magic bullet. If that bullet doesn't work, gravity will, hell, they're gettin' the gravity regardless.
The girls are really starting to hit their stride, tuesday will finish week three of 12/12. I have upped the strength of their nutes and so far not a single sign of burn. Over the next three weeks I plan on giving them as much as they can stand instead of my low steady doses of nutes. From what I've noticed, weeks four, five and six seem to be when the plants require their strongest doses of nutes. Week seven I'll start cutting back the strength and assess their progress at that point and see how much more time might be needed to finish. The last week of flowering I only give them water and molasses.
