Ohhh ISK, just love your girls, nice job on the trelis support. My crystal ball shows some nice fat colas in the future. I wanted to ask...have you found a convenient measuring "spoon" size for 7grams of MaxiBloom? And, if you don't mind...do you have to add it to warm water first to dissolve it? I might want to try the Lucas Formula with it on a side project.
A 5ml measuring spoon is damn close, but I use gun powder scales (in grains) which are rather precise, so I measure 107.4 grains which equals 7 grams
I fill a glass jar with hot tap water then add the GH powder, next I use a milk frothier to mix it.
The milk frothier works so well, as before I would do the shake method which is a royal pain in the ass and after 5 minutes there would still be some residue on the bottom....about 60 seconds of the frothier, let settle, give it a few more spins if any residue settles. (PS: frothier are cheap ($7) but it becomes red from the GH so I have another one for my "cafe con leche")
I then add my cal-mag to 4 litres of water, add the GH mix and pH + to an "orange/yellow" colour, then pour into 6 glass jars for individual servings (about 660ml each).
PS I had found it would start to "smell bad" in about 3 days if stored in the plastic jug...no problems stored in glass
BTW: I only have one plant, so one batch will last me 6 days
