That is correct. To be more specific: per gallon I use 3.6g Jack’s Hydro 5-12-26, 2.4g Calcium Nitrate, and 1.2g Epsom, each of which has been made into a concentrated stock solution (see attachment) to make mixing easier on my gimpy ass.

When it’s time to mix up more for the rez, I just use a syringe to measure equal parts of the stock solutions. Each syringe is marked with tape for a “fill line” at 40ml, for a three gallon batch, so I just go down the line and “measure, squirt, stir”.
The plants are in 2-gallon fabric pots filled with Canna coco with a thick layer of crushed pumice on top to slow evaporation and let the roots fill the pots all the way to the top. They are in a flood and drain setup that is currently set for three fifteen minute flood cycles during lights on.
Here’s a pic from last week… The roots are way crazier now, but it’s currently lights off.
I’ve got six Marauder plants and a revegged GG4 S1 in that 2’ x 4’ tent, and I’m really counting on some males showing soon to free up more room. Normally I end up with three or four plants, which will fill the tent nicely.
It’s a jungle in there, disorder and confusion everywhere
