Nettle FPJ (fermented plant juice) - Almost free grow nute

[GMO]

Nettles (Stinging European)

approx. N-P-K
5.6-0.7-3.7

as well as:

Iron
Copper
Zinc
Magnesium
Calcium

Create a nettle FPJ by filling a bucket with the leaves and stems and bruising the foliage. Cover with water and weigh down the nettles with a brick, paving stone. Only fill three-quarters of the bucket with water to allow room for the foam that will be created during the fermenting process.

Leave the bucket in a semi-sunny area, away from the house if smells is an issue. Leave the mix for one to three weeks to ferment, stirring every couple of days until it stops bubbling.

Finally, strain out the nettles and dilute the concoction at one part fertilizer to 10 parts water for watering plants or 1:20 for direct foliar application. Undiluted mix makes an excellent organic herbicide and can be added to the compost bin to stimulate decomposition.

Nice write up GMO.

a nice lil vid that covers some uses and also a FPJ method

I have been using Canna mutes, led lights. As I have moved into flower I get deficiencies. The received wisdom is Cal-mag. I tried my next grow with Cal-mag - only to get same deficiencies. In frustration I stopped Canna units and started just feeding nettle tea. I am now in mid flower and have a beautiful green plant with no deficiencies. So they are now in Canna Terra soil, and are fed exclusively with nettle tea and are thriving.

Theirs not really a call for calmag these days with most base ferts if you use enough, when i look at lots of deficiencies online nowadays, 80 to 90% of them are basic mistakes and just underfeeding. If you were using chemical base ferts on a flowering plant an EC around 1.6 in bloom would prevent most deficiencies happening with correct ph. .

One of most common mistakes is when people flip to bloom the plants are stretching like mad they just carry on using same dose of feed they have been using when plants in veg and they dont up base fert EC ready for plants in bloom . For those first 3 weeks plant wallops down ferts so the base ferts need upping quite a bit to prevent shit like calcium def occurring . Most common deficiency you tend to see if you dont is calcium def around 4 to 5 weeks into 12/12 quite a lot of the time.
