Thanks, asublimeutopia. Glad you're enjoying the pics.
I pulled Plant 3 and Plant 4 out of the cab earlier for a quick photo session.
All I've been giving them is tap water filtered through a Small Boy (with the upgraded carbon) plus somewhere around 1 tsp/gal of General Organics CaMg+. My tap water is VERY low on minerals, so I've been adding that most waterings. A few days ago I gave them an AACT brewed with worm castings, alaskan humus, a little fish hydrolysate, and a dab of molasses.
Anyway, here are some pics of Plant 3 and Plant 4. I didn't drag the other two out... Plant 1 is pretty interesting, though... Pics to come.
