After 3-4 weeks try this recipe - you will need to adjust for the amount of water you will use. I use this for 3 and 5 gallon fabric pots. I start out watering every 3-4 days but by the end of veg going into flower I end up watering every other day until they finish.
Per 2 Gallons Water - Veg:
2 teaspoons Cal Mag
2 teaspoons Grow Big
1 tablespoon Big Bloom
3 teaspoons PH Down
Add more PH Down as needed to PH = 6.50
When watering 4 plants in 5 gallon fabric pots, I use 1.5 gallons per plant, or 6 gallons each watering session. I will mix the first 2 gallon batch, water all 4 plants, wait 30 minutes to soak, then mix batch 2 of the same recipe above. Water, wait 30 minutes.
I then mix a 3rd batch of "plain" water as follows:
Per 2 Gallons Water - Final Runoff:
2 teaspoons Cal Mag
3 teaspoons PH Down
Add more PH Down as needed to PH = 6.50
I am using Fox Farms Happy Frog medium. Be careful with the Big Bloom, I use it every time I water, but I never use more than 1 tablespoon per 2 gallons or I risk damage to the plants, confirmed by trial and error.
When I switch to flower, I use both Grow Big and Tiger Bloom to start, and then alternate watering using just Tiger Bloom and only use Grow Big every other watering. I also add Sweet and Sticky to the 2nd and 3rd batch of water. The sugar in the Sweet and Sticky is food for the roots and I want the sugar to stay in the roots as much as possible, so the final watering is plain water with just Sweet and Sticky. This final rinse also helps to wash the fertilizer salts out of the roots while leaving the sugar behind.
Per 2 Gallons Water - Flower, batch 1:
2 teaspoons Cal Mag
2 teaspoons Grow Big
2 teaspoons Tiger Bloom
1 tablespoon Big Bloom
3 teaspoons PH Down
Add more PH Down as needed to PH = 6.50
Per 2 Gallons Water - Flower, batch 2:
2 teaspoons Cal Mag
4 teaspoons Tiger Bloom
1 tablespoon Big Bloom
2 teaspoons Humbolt Sweet and Sticky
3 teaspoons PH Down
Add more PH Down as needed to PH = 6.50
Per 2 Gallons Water - Flower, Final Runoff:
2 teaspoons Cal Mag
2 teaspoons Humbolt Sweet and Sticky
3 teaspoons PH Down
Add more PH Down as needed to PH = 6.50
By week 4 in flower I am no longer adding Grow Big, and instead add 4-8 teaspoons Tiger Bloom per 2 gallons water. I will continue to use Big Bloom and Sweet and Sticky until the end.
Here is my last batch just before transplanting into 5 gallon fabric pots (they are a little dry in the picture, they were taking water every 36 hours at this point, hence transplanting to 5 gallon pots. It didn't get me much more time, they are still taking water every 48 hours now).
