that's the stuff Ive been using right now. it's powdered form, I always eyeball it, what I have noticed is everytime I thought I went overboard the next morning the plants look super ubber healthy almost bluer than green... also I have yet to actually over do it even on seedlings. Since then Ive been using it here and there in the flower room where I normally use nothing but tap water and I was starting to wonder if I could actually overdo it to the point that it might ruin the taste but so far so good. nothing but healthy plants!
I be down with WHF
Rock their kelp a lot myself, actually
Definitely something babies can handle more than other amendments
Do u know what percentage your at rn in your mix, roughly?
Of total volume
..That's what I prefer as a measurement
Once you start topdressing tho, it gets harder to measure
And harder to make it burn clean and ultra smooth
Not that you won't see great results meanwhile
It's fkn packed with great stuff
..what size pots are you flowering in?
The smaller, the higher I might recommend
(Harder to correct or weaken a big batch)
1.5% if doing over 20gal vs 2.5% total volume, if doing a 10 gal less, for example
Unsoaked, aka pre-expansion numbers shown
I measure
then soak then sprinkle, then
wait.
No topdress or foliar after, unless cloning
Kelp my fav amendment to add last, other than aeration of course
