I give Bud Candy @ days 30 & 45 (ish) and I think that Vortex got a touch of Roots Organics HP2 at about week 5-6. Nothing Crazy. I try to keep it simple.
I think perfecting your ratio is imperative. Getting your fade to hit just at the right time, I like to see yellow/fade just touching the calyx at chop. If I can make this happen with no need for adjustments the plant never sees a deficiency or stress from over feeding. Get your ratios on point, run a clone a couple times and write down what ratios you used previously.
Ratios I use (transplanting from 2 gal pots):
Keepers:
-Vortex: Just under 3 Gal SS w/ .5 Gal top feed @ 21 Days.
-Bubba Kush x Querkle: 1 Gal SS
-JillyBean (transplanted from 2gal w/ .5gal SS in Veg): 3.5 Gal SS w/ 1 Gal top feed @ 21 Days.
Now, these are for my cuts... other phenos/genos and environmental conditions change these ratios, but it's a good jumping off point for some.
Other SS Pointers:
Here's one SS thing that most people dont find out until too late:
Cheese Strains. It's all about top feeding. I've ran a ton of cheese cuts in SS w/ great success (and a few failures)
Here is what I have success with:
-2 Gal Veg pot w/ only base soil for Veg, cheese strains tend to get root bound easier than most.
-transplant into
-7 Gal Flower pot w/ 1 gal of SS at the bottom and filled w/ 3 Gal of base soil, leaving enough room on top for a heavy 1 Gal top feeding at 21-28 days.
Well... that's all I can think of for now, smoking on some Vortex this morning, hope it came through clear enough.
