It's handy guide.
That guy is a foliar addict and it's interesting.

Cannabis, thank you for sharing your experiences Bordeaux and mites. I can't spray the large plants with that because I'll definitely get quite a bit on the flowers. I might try it on the seedlings before they begin to flower.
What I'm going to try is planting marigolds in each 5 gallon pot alongside the cannabis to deter unwanted insects. I hope that works.
This is weird...
The yellow leaves on the seedlings are showing very little improvement... maybe none. But the healthy leaves are deeper green. I expected a better (different) outcome. I sprayed the older plants anyway and those seem to be reacting similarly.
Any suggestions?
Not to worry, it did sit there for a few hours and probably did its thing.
Below is part of the guide I use, distributed by the people who make and use NFTG
It is not meant to be anything but someones opinion, but I
follow the advice.
Foliar Feeding Recipes:
1) Feed early in the day or in the evening, when the sun/light is weaker. This will keep the
sun/light from burning the leaves, as water droplets can act like a magnifying glass.
Stomata are more likely to be open during these times as well.
2) Do not spray if the temperature is over 80F or in the bright sun
3) Use a surfactant. Surfactants reduce the surface tension of the water, spreading it over the
leaf surface. More surface area = more absorption. Yucca is an awesome organic
surfactant.
4) Hit everything. Don’t forget to spray the tops and bottoms of the leaves for maximum
absorption. - remember, stomata are abundant on the undersides of the leaves.
5) When mixing up your formulation, whether mineral, organic fertilization or compost tea,
use non-chlorinated, well oxygenated water. Bubble air through chlorinated tap water for
2 hours or leave it to off-gas overnight.
6) Make sure mineral ingredients are dissolved and the solution is very dilute. Chemicals in
high concentration tend to ‘burn’ foliage and leave a salt residue. Suggestion is to
NEVER add any salt base nutrient into your teas.
7) Young transplants prefer a more alkaline solution (pH 7.0) while older growth like a
somewhat more acidic (pH 6.2) spray. If you are concerned about Olympus up (calcium),
you can use baking soda to raise pH and apple cider vinegar to lower the pH of your
spray.
8) Spray with a fine sprayer for foliar fertilization and a coarser, low pressure sprayer for
compost teas. The microbes in compost tea need large protective water droplets. Harsh
ultraviolet rays can kill microbes in compost tea.
There are some recipes I omit them as
I am not trying to sell anyones stuff and they are mostly based on NFTG products
I might not manifold the next set (the ones that are currently babies) but I want to leave that option open. Or, if I can build the grow room very soon, I might try doing vertical SCROGs on each wall.
BTW, it started raining about an hour ago... very light sprinkles at first. Now it's becoming a light rain so most of the foliar spray will washed off. At least it was there for several hours.
