Anything i could get from a local garden centre
Cannabis is a regular plant.
Don't listen to the people saying that it has to have Dr Zoggs Monkey Voodoo Trademarked Specialist Horribly Expensive Food. That's elitist commercial crap.
Most plants have three stages. There are standard nutes at any garden centre tailored for each of these cycles:
- vegetative
- grow
- flower (or fruit)
Just ask for "a flowering stage supplement feed please, preferably organic"
Avoid slow release
These are usually granulated or pellets, and are meant for a top soil scatter and feeds as the person waters. They will say something like this the label,
apply x grams per square metre every 3-4 months.
If you use that on weed plants directly, you run a risk of nutrient burn.
Also, seeing as your girl is budding, she will taste nasty if she gets too much feed just before harvesting and curing.
