Hi Jats,
As Knickers, I don't know THC A+B. Google says a lot about THC but not regarding Total Horticultural concentrate
I use flora series from GHE, well known in hydro.
Seems it works good in coco, with a good PH buffer.
As I told you, my young girls were not very happy : yellow head and leaves, plants beginning to die...
I know my mistake : the first hand water in little pot was without nuts...
This is an error of soil grower : never nut before 3week because nuts are already in the soil.
-> no nuts in the coco!!!!!!!
second hand water direclty in autopot with nuts but they really suffered.
I think now they are alive
as you can see on the picture. we can see the head is green again but we can see below the head that they had a hard time...
see the pics below + my grow room (autopot/ drybox/ mother+cut)
-> the cut (northernlight + white diesel from sensiseeds) are for my second box where I will do a grow 100% soil because I'm a coco newbie as you can see and I want to have something to smoke if I fail the coco project
Bye
