This is the schedule Im using with good results.
One thing I seen on several grows with GG, is that around weeks 2.5-3, many strains start to develop a huge Calcium Deficiency. As far as I can tell, this cures that possibility.
This schedule, was an updated GG Regime, from another forum.
First week, they get nothing. I myself, plant them in Promix BX, which already has enough Mycorrhizae, at this point, and then
Start feed at week 2.
I also use Worm Castings, and Myco Supreme.
Worm Castings, every watering.
Something else to think about.
If one uses a lighter type Medium, like Promix BX/HP, then one needs to rethink the actual amount of Medium, that is in the container.
Some people, may use the container size they are growing in to determine amount of medium. 5 gallon container, holds 5 Gallons, Right??
Depends. Depends on the Density of the Medium, and how hard the Medium, is compacted into the container.
If a 20 Gallon Container, truly holds 20 gallons, will only hold 9.1 GALLONS, of Promix BX.
Some containers like the Vivosun Fabric Bags I bought, are actually 13.9 Gallons. 15.9 x 15.9 x 11.9 = total cubic inches divided by 231 which is how many cubic inches, in a 1 gallon container= 13.9 Gallons.
So some may be greatly overfertilizing their plants, if they do not accurately calculate real medium volume.
Consider this??
Ever see one of the Promix BX/HP 3.8 Cubic Foot Bales?? 65lbs-70lbs
Those, are in reality, only 28.4 Gallons of medium. 1 of them will fill 2x 20 gallon Totes, with some left over. Which means if one calculated fertilizer amount by container size, vs actual Medium Volume, they will be greatly overfertilized by 55.5%.
And also consider, containers are not completely filled, and stuffed, to the top either, thus further reducing actual Medium amount.
This is for an 8 weeks flowering strain. Slight adjustment need to be taken into account, if the strain is longer flowering than 60 days.
I also use Worm Castings every watering.
And inoculate soil every 60 days, and when transplanting with Myco Supreme.
I also use AZOMITE, as my Rock Dust Source.
